A reaction test may report one number in milliseconds, but that number rarely reflects just one thing. When you perform a keyboard reaction time test, the measured result is the sum of an entire chain: seeing the stimulus, deciding to respond, sending a motor command, moving your finger, pressing the key, the keyboard scanning that press, the firmware processing it, the USB layer communicating it, the operating system handling the event, and finally the browser or application recording the timestamp.
That chain matters. It means two people with identical neural speed can post different scores depending on their hardware. It also means a person can improve their score by upgrading a display, without their actual reflexes changing at all.
Keyboard reaction speed is relevant across a wide range of situations: FPS and tactical shooters where ability timing and movement matter, rhythm games where millisecond precision separates grades, fighting games where punish windows can be measured in single frames, racing games where braking cues demand instant responses, and even accessibility and human-computer interaction research where key press latency is a controlled variable.
This article explains how keyboard reaction measurement works, what the numbers actually mean, how hardware affects results, and how to test and interpret your own performance accurately.
What Is a Keyboard Reaction Time Test?
A keyboard reaction time test measures the delay between the appearance or sound of a stimulus and the user's key press response, reported in milliseconds. The test captures a complete response chain ā not just the speed of a nerve impulse, but the entire path from stimulus to registered input.
That chain includes several distinct stages:
- Stimulus presentation: a visual cue appears on the display, or an audio cue plays.
- Sensory detection: the eye or ear receives the signal.
- Neural processing: the brain identifies the cue and decides to respond.
- Motor command: the brain sends a signal to the finger muscles.
- Finger movement: the finger accelerates and travels to the key.
- Key actuation: the switch registers a press at its actuation point.
- System registration: the keyboard reports the input to the operating system, which passes it to the browser or application.
Different test designs target different parts of this chain. Three common task types exist:
- Simple reaction time: one stimulus, one key. Press as soon as you see or hear it.
- Choice reaction time: multiple stimuli mapped to different keys. The brain must identify the correct response before acting.
- Go/no-go tasks: respond to one stimulus, ignore another. Requires active inhibition as well as initiation.
Simple visual key-press tests are the most common format online. They remove the decision component as much as possible, so the result is dominated by detection speed, motor initiation, and the full input chain.
How a Keyboard Reaction Time Test Works
The process unfolds as a sequence:
- A visual or auditory cue appears after a variable or randomized delay.
- The sensory system detects the signal.
- The brain processes the cue and decides to respond.
- A motor command travels to the finger.
- The finger moves and depresses the key to its actuation point.
- The keyboard's controller detects actuation and reports the event.
- The input reaches the operating system and then the browser or test application.
- The test records the elapsed time between stimulus and registered keypress.
Simplified:
Stimulus ā Sensory Processing ā Decision ā Motor Command ā Finger Movement ā Key Actuation ā Input Registration ā Recorded Result
Browser-based tests measure the full chain from their perspective. The timer typically starts when the DOM presents the stimulus and stops when a keydown event fires. This means the result includes not just your neural speed but also display rendering, input device latency, browser event timing, and operating system scheduling.
This is not a flaw. It is just what the test measures. Understanding the full chain is essential for interpreting results correctly.
What Is a Good Keyboard Reaction Time?
For a simple visual key-press task ā the most common type of online reaction test ā typical results in healthy adults generally fall somewhere between roughly 150 ms and 300 ms. Most people cluster toward the middle of that range under relaxed, focused conditions.
Those numbers are orientation estimates for a specific type of test, not clinical norms. Results depend on the display refresh rate, the browser environment, the keyboard used, the person's age, current fatigue level, how many warm-up trials were taken, and whether anticipation was a factor. A result from one website on one machine should not be compared directly with a result from a different site on different hardware.
| Performance Band | Approximate Response Range | General Interpretation |
|---|---|---|
| Fast | Below 180 ms | Very quick response under a simple visual key-press task |
| Good | 180ā220 ms | Strong response speed for an online visual test |
| Typical | 220ā280 ms | Common range across many simple online tasks |
| Slower | Above 280 ms | May reflect individual factors, task design, fatigue, or device conditions |
Important: these ranges describe orientation only. They are not medical benchmarks, clinical norms, or standardized scientific thresholds. Your own average across multiple trials on consistent hardware is a more meaningful baseline than any single attempt or cross-device comparison.
To measure your own response speed with a consistent methodology, use the Reaction Time Test and track your average across several attempts.
Keyboard Reaction Time vs Keyboard Latency
These are two different things, and conflating them produces confused expectations.
Keyboard reaction time refers to the total measured response that a test records: your neural speed, motor execution, and the device chain all combined into one number.
Keyboard input latency refers only to the hardware-side delay between physical key actuation and the moment the computer registers that input. It is one component of the full chain, not the whole thing.
A person with fast natural reflexes can still produce slower test scores on a high-latency input chain. A person with average reflexes can post relatively low scores on a very optimized system. Neither number tells you the pure neural speed of the user in isolation.
| Measurement | What It Represents | Typical Unit |
|---|---|---|
| Human Reaction Time | Sensory processing plus motor response | ms |
| Keyboard Input Latency | Hardware delay from actuation to registered event | ms |
| Display Frame Time | Time between screen refresh opportunities | ms |
| Network Ping | Network round-trip delay | ms |
Network ping is not a factor in a local browser reaction test. The measurement happens on your machine. Ping only matters if the test architecture specifically requires a network round-trip for timing, which standard reaction tests do not.
Keyboard vs Mouse Reaction Time
The comparison is more complicated than it looks. Neither device is universally faster. Results depend on the specific test, the hardware, the finger position at the moment of the cue, and the user's experience with each input method.
Key differences between the two devices:
- Finger resting position: if a finger rests on a key, the movement distance to actuation can be very short. A mouse button click from a resting position also involves minimal movement, but the mechanics differ.
- Actuation travel: keyboard switches vary widely. Some actuate at 1ā2 mm; others at 4 mm or more. Mouse buttons typically have short, consistent travel.
- Debounce behavior: both keyboards and mice implement debounce logic; implementation varies across products.
- Device latency: both device categories span a wide latency range depending on design, polling rate, and firmware.
- Task context: in games, keys handle movement and abilities while mice handle aim and fire. Testing either in isolation captures a different action pattern than real gameplay.
| Factor | Keyboard | Mouse |
|---|---|---|
| Actuation | Key switch mechanism | Mouse button switch |
| Finger Movement | Depends on key and actuation point | Usually a short button depression |
| Device Delay | Varies by keyboard design and firmware | Varies by mouse design and firmware |
| Primary Gaming Use | Movement, abilities, actions, cooldowns | Aim, fire, selection |
| Test Result | Reflects full measurement chain | Reflects full measurement chain |
What Affects Keyboard Reaction Test Results?
Human Processing Speed
The biological component dominates the total response time. The brain must detect the stimulus, allocate attention, decide to act, and issue a motor command before the finger even starts moving. Simple visual processing introduces a baseline delay that no hardware upgrade can reduce below a physiological floor. Factors like focus, anticipation, and trial-to-trial variability mean that consecutive attempts from the same person rarely produce identical results.
Keyboard Input Latency
Not all keyboards register input at the same speed. Latency differences between devices arise from switch design, firmware implementation, scan rate, debounce method, and USB communication behavior. The gap between a well-optimized gaming keyboard and a low-cost office keyboard can range from under 1 ms to several milliseconds. That is a small portion of the full response chain ā but at high levels of performance, it is not negligible.
Polling Rate
Polling rate describes how frequently a keyboard reports its state to the computer. A keyboard running at 125 Hz sends an update every 8 ms. At 1000 Hz, that interval drops to 1 ms. At 8000 Hz, currently found in some high-end gaming peripherals, it drops to 0.125 ms.
A higher polling rate reduces the maximum time the system must wait between input reports. However, polling rate alone does not define total end-to-end latency. Firmware scan timing, debounce delay, USB protocol overhead, and OS scheduling all contribute. A keyboard at 1000 Hz with high debounce delay can still post worse actual latency than a well-optimized 500 Hz device.
Keyboard Scan Rate
Scan rate and polling rate are related but not the same. Scan rate refers to how quickly the keyboard's internal controller scans its switch matrix to detect key states. A keyboard might scan its matrix more frequently than it reports to the host ā or the two intervals might be tightly coupled depending on the firmware design. Both contribute to the overall input response time, but treating them as identical oversimplifies how keyboards actually work.
Debounce Delay
Mechanical contacts can produce multiple brief electrical transitions when a key is pressed or released ā a phenomenon called contact bounce. Keyboard firmware uses debounce logic to ignore these spurious signals and register only the intended press. Different implementations exist: time-based debounce waits a fixed interval after detecting a transition; algorithmic approaches may sample over a short window. The implementation affects how quickly the keyboard confidently registers an input. Aggressive debounce settings can introduce several milliseconds of intentional delay. Some modern gaming keyboards advertise low or adjustable debounce to minimize this contribution to latency.
Actuation Point
Actuation point is the travel distance at which a switch registers. A switch that actuates at 1.5 mm requires less physical movement than one that actuates at 4 mm. Less travel can mean the finger reaches the registration point sooner ā but only if the finger is already positioned correctly and applying force in a consistent direction. Keyboards with adjustable actuation allow users to set the trigger point very shallow, or even to implement rapid trigger behavior where the key resets and reactivates over a very small travel distance.
Display Refresh Rate
The visual stimulus must appear on screen before the response chain can begin. Display frame timing introduces a variable delay based on where in the current refresh cycle the stimulus is ready to be presented.
| Refresh Rate | Frame Interval |
|---|---|
| 60 Hz | ā 16.67 ms |
| 120 Hz | ā 8.33 ms |
| 144 Hz | ā 6.94 ms |
| 240 Hz | ā 4.17 ms |
These numbers represent the maximum wait before a frame can be presented ā not the guaranteed improvement to your measured reaction time. Still, in repeated trials, a 60 Hz display introduces more average stimulus presentation delay than a 240 Hz display. That difference can show up in test averages, particularly across many trials.
Fatigue and Attention
Sleep deprivation measurably slows reaction time. Mental fatigue from prolonged testing introduces drift. Repeated attempts within a short session can create anticipation ā the user begins predicting the stimulus rather than reacting to it, which can produce artificially fast scores or increased variability. Distractions, anxiety, and even excessive focus can all influence results in different directions.
Mechanical vs Membrane vs Optical vs Hall Effect Keyboards
Mechanical Keyboards
Mechanical keyboards use individual switches for each key. Each switch contains a physical mechanism ā typically a stem riding on a spring ā that actuates at a defined travel distance. Switch designs vary considerably: linear switches actuate smoothly without tactile feedback; tactile switches provide a bump at the actuation point; clicky switches add audible feedback. Actuation distances, spring weights, and debounce behavior differ between switch models. Mechanical keyboards span a wide range of input latency depending on the firmware, debounce implementation, and polling configuration ā not just the switch type.
Membrane Keyboards
Membrane keyboards register input through pressure on a layered membrane beneath the keycap. They are common in office and budget contexts. The claim that membrane keyboards are always slower than mechanical keyboards is an oversimplification. While many low-cost membrane products have higher latency than well-optimized mechanical keyboards, membrane technology itself does not define a fixed latency ceiling. The firmware, polling configuration, and debounce implementation still determine actual behavior.
Optical Keyboards
Optical switches use an infrared light beam to detect key actuation rather than a physical metal contact. Because there is no contact bounce in the traditional sense, optical keyboards can implement debounce differently ā sometimes with shorter delays or without the bounce-settling wait that contact switches require. This does not automatically guarantee the lowest latency in all cases, since firmware and system implementation still matter, but it removes one of the traditional sources of debounce delay.
Hall Effect Keyboards
Hall effect switches use a magnet and a sensor to detect key position based on magnetic field strength. Because the detection is analog rather than contact-based, the keyboard can identify exactly how far a key has traveled at any point. This enables adjustable actuation ā users can set the actuation depth in fractions of a millimeter ā and rapid trigger functionality, where the key can reactivate without returning to the full rest position. These features are particularly relevant for competitive gaming, where repeated directional inputs benefit from faster key re-registration. Hall effect keyboards are increasingly common in competitive FPS contexts.
Key distinction: No switch technology directly improves a person's neural reaction speed. Lower input latency and shorter actuation reduce the hardware side of the response chain. They do not change how fast the brain detects and processes a visual stimulus.
Does Rapid Trigger Improve Reaction Time?
Rapid trigger changes how a keyboard handles key re-registration during repeated movement. In a standard switch, the key must return above the reset point ā typically close to or above the original actuation point ā before it can register again. Rapid trigger allows the key to re-actuate after traveling only a small distance in the upward direction, enabling faster repeated presses or quicker directional changes without lifting the finger fully.
This matters for specific actions:
- Counter-strafing in games like Counter-Strike 2 and Valorant, where releasing and re-pressing a directional key quickly is a learned mechanical skill.
- Repeated directional input in platform fighters or any game requiring rapid alternation of movement keys.
- Rhythm game charts with fast repeated note patterns on the same column or key.
For a simple, single-press reaction test ā where you wait for a cue and press once ā rapid trigger has little to no effect. The test records a single keydown event. Key reset behavior is irrelevant for that specific task. The brain's processing time and motor initiation dominate the result, and no keyboard setting changes either of those.
Rapid trigger is a real, useful feature for specific competitive gameplay scenarios. It is not a reaction time enhancement in the neural sense.
Why Keyboard Reaction Speed Matters in Gaming
FPS Games
In games like Counter-Strike 2, Valorant, and Apex Legends, keyboard reaction speed is most relevant for movement inputs: starting or stopping a strafe, crouching during an exchange, jumping to avoid a predictable shot, or activating an ability at the right moment. These actions are often combinations of decision speed, muscle memory, and crosshair discipline ā not pure reflex alone.
Game sense, crosshair placement, and anticipation contribute at least as much as raw reaction time in most engagements. A player who reads a situation correctly and pre-positions will outperform a player with faster reactions who guesses wrong.
Fighting Games
Fighting games involve some of the most demanding reaction contexts in competitive gaming. Punish windows for certain moves can be as short as 2ā6 frames at 60 fps, meaning 33ā100 ms of available reaction time. At that scale, pure visual reaction to a move's animation is often not fast enough ā players instead rely on recognizing patterns, predicting opponents, and reacting to startup frames they have learned to identify. True reaction to unseen inputs at frame-tight windows is rare; anticipation and pattern recognition do most of the work.
Rhythm Games
Rhythm games like osu!, Quaver, or similar titles demand consistent millisecond-level timing precision across repeated key presses. Here, the concern is less about speed and more about consistent offset ā pressing a key at exactly the right moment relative to a visual or audio cue. Keyboard input latency and display timing directly affect offset behavior, which is why many rhythm game players calibrate their offset in-game to compensate for their specific hardware chain.
Racing Games
In sim racing or arcade racing contexts, braking cues, reaction to start lights, and corrective steering inputs all depend on quick keyboard response. Start lights in particular are a classic simple reaction test scenario: see the light, act immediately. Display latency and keyboard response time both contribute to the total response chain here.
Do Gaming Keyboards Improve Reaction Time?
A lower-latency keyboard can reduce the hardware portion of the total response chain. It does not change how fast your brain processes a visual stimulus. These are different things.
The distinction worth drawing:
- Human improvement: practicing reaction drills, improving sleep, reducing cognitive load.
- Hardware improvement: reducing keyboard latency, optimizing polling rate, using a higher refresh rate display.
- Measurement improvement: using more consistent test conditions so scores better reflect actual performance.
- Gameplay responsiveness: the subjective and objective feel of input response in-game, which involves more than just latency numbers.
For most users, the hardware contribution to a browser reaction test score is small relative to the human component. The difference between a 125 Hz budget keyboard and a well-optimized 1000 Hz gaming keyboard is real, but it is a single-digit to low double-digit millisecond difference at most. If your average result is 240 ms, that gap matters much less than reducing fatigue or improving consistency.
At the highest level of competitive play, hardware margins tighten and these differences become more meaningful. Marketing claims, however, often describe these differences in ways that exaggerate their practical impact on performance outcomes.
How to Improve Keyboard Reaction Speed
1. Practice Random-Cue Reaction Drills
Tests and drills that randomize the cue timing train genuine reactive speed. Predictable timing allows anticipation, which produces faster but less meaningful scores. The randomized wait before a stimulus is what makes a reaction test measure actual reaction rather than expectation.
2. Avoid Predicting the Stimulus
Anticipating the cue and pressing slightly early can produce artificially fast times on a test that doesn't penalize early presses. It does not reflect faster genuine reactions. If a test does track false starts, treat them as information ā you were predicting rather than reacting.
3. Keep a Consistent Finger Position
If your finger rests farther from the key, your movement distance increases and your scores will reflect that. Maintaining a consistent starting position between attempts makes your results more comparable and reflects consistent behavior closer to what you'd actually use in practice.
4. Practice Relevant Game Actions
Generic reaction drills improve generic reaction. Practicing specific game actions ā counter-strafing, punish inputs, rhythm game columns ā builds the motor patterns and learned anticipation relevant to that context. Task-specific training transfers more effectively than abstract speed work.
5. Improve Sleep and Recovery
Sleep deprivation is one of the most consistent ways to slow reaction time. Even modest sleep restriction produces measurable effects on processing speed. Recovery between heavy training or play sessions also matters ā accumulated mental fatigue degrades consistency.
6. Reduce Unnecessary System Latency
Stable frame rate, a consistent display configuration, and minimal background system load all contribute to a cleaner, lower-latency test environment. Unstable frame rates introduce frame timing variability that can affect when stimuli appear on screen. Closing unnecessary heavy applications reduces OS scheduling noise.
7. Track Averages, Not Single Scores
One fast result is not a meaningful data point. Individual trials have high variance. Your median or average across 10ā20 attempts tells you far more than your best single score. Tracking your average over multiple sessions, on the same hardware, is the only reliable way to observe whether you're actually improving.
For additional training strategies, see the guide on how to improve reaction time.
How to Get More Accurate Keyboard Reaction Test Results
- Use the same device for comparisons. Don't compare a phone tap score with a desktop keyboard score.
- Use the same keyboard across sessions when tracking progress.
- Keep your finger resting near the key before the cue appears.
- Close unnecessary applications that create background CPU and rendering load.
- Use a stable display configuration. Toggling refresh rate or resolution between sessions changes the baseline.
- Avoid guessing or predicting the stimulus timing.
- Perform at least 10 trials per session and use the average or median.
- Discard obvious false starts only if the test protocol explicitly supports that.
- Don't compare your scores directly with scores from different websites or different hardware configurations. The test chain differs between them.
- Compare yourself against your own baseline first, tracked consistently on the same setup.
Consistency in test conditions is more valuable than any single performance number.
Keyboard Reaction Time and Monitor Refresh Rate
Display refresh rate affects keyboard reaction test results through frame timing. When a test is ready to present a stimulus, it must wait for the next available display frame. At 60 Hz, that wait can be up to 16.67 ms. At 240 Hz, the maximum wait is 4.17 ms.
| Refresh Rate | Frame Interval |
|---|---|
| 60 Hz | ā 16.67 ms |
| 120 Hz | ā 8.33 ms |
| 144 Hz | ā 6.94 ms |
| 240 Hz | ā 4.17 ms |
Because this delay is variable ā the stimulus could appear at any point in the current refresh cycle ā it adds noise to individual trial results. Over many trials, the average stimulus presentation delay is roughly half the frame interval. At 60 Hz, that is approximately 8 ms of average added measurement uncertainty. At 240 Hz, it is closer to 2 ms.
This does not mean switching from a 60 Hz to a 240 Hz display makes your brain react faster by 12 ms. It means the measurement environment has less frame-timing noise at higher refresh rates, and the stimulus becomes visible sooner on average. Your actual neural reaction time is unchanged.
Common Myths About Keyboard Reaction Time
- A gaming keyboard automatically makes your brain react faster.
Hardware reduces input latency. It does not change neural processing speed. The brain's reaction to a visual stimulus is not affected by what keyboard is plugged in. - The highest polling rate always means the lowest total latency.
Polling rate is one factor. Firmware scan behavior, debounce delay, and OS handling all contribute. A high polling rate with a poorly implemented debounce can still produce worse actual latency than a well-optimized lower polling rate device. - Mechanical keyboards are always faster than every membrane keyboard.
Switch technology does not define a device's full latency. A well-optimized membrane keyboard can outperform a mechanical keyboard with aggressive debounce settings. Both categories span a wide range. - One very fast result represents your true reaction time.
Single trials have high variance. A single fast score may reflect a good moment, anticipation, or random measurement variation. Averages over many trials are meaningful; individual outliers are not. - Rapid trigger improves every type of reaction test.
Rapid trigger affects key re-registration behavior during repeated movement inputs. For a single-press reaction test, it has no relevant effect. - Internet ping determines local keyboard reaction test results.
Standard local browser reaction tests do not involve a network round-trip. Ping is not part of the measurement chain. - Faster actuation alone guarantees better gaming performance.
Actuation depth reduces the physical movement component of input time. It does not improve crosshair placement, game sense, decision speed, or any other skill component that contributes to actual in-game performance.
How Should You Interpret Your Results?
A single attempt tells you almost nothing. A consistent average over many attempts on the same hardware tells you quite a lot.
When reviewing your results:
- Look at the median or average across at least 10 trials.
- Note the variance. Consistent scores suggest a stable measurement environment and consistent performance. High variance suggests anticipation, distraction, or hardware noise.
- Establish your own personal baseline on your own hardware.
- Track that baseline over time on the same device to observe genuine change.
- Do not compare your score from one website with someone else's score from a different website on different hardware. The measurement chains are different.
For context on how results compare across different age groups and conditions, the average reaction time guide covers what typical distributions look like and what factors shift them.
Your primary comparison point should be yourself ā your own history, on your own consistent setup, tracked over time.
Frequently Asked Questions
1. What is a good keyboard reaction time?
For a simple visual key-press test, a result below 180 ms is considered fast, 180ā220 ms is strong, and 220ā280 ms is typical. Results above 280 ms may reflect individual variation, fatigue, or hardware conditions. These are orientation ranges for online tests, not medical or clinical benchmarks.
2. Is keyboard reaction time faster than mouse reaction time?
Neither input device is universally faster. Results depend on the specific test design, the hardware used, finger position, and the user's experience with each device. Both keyboards and mice span wide latency ranges across different products.
3. Does keyboard polling rate affect reaction tests?
Yes, polling rate can contribute to keyboard input latency. A higher polling rate reduces the maximum interval between input reports. However, polling rate is one factor among several, including firmware scan rate, debounce behavior, and OS handling. A higher polling rate does not guarantee the lowest total latency.
4. Is 1000 Hz better than 125 Hz for reaction testing?
A 1000 Hz polling interval of 1 ms is shorter than a 125 Hz polling interval of 8 ms. In principle, 1000 Hz reduces the maximum polling-related delay. In practice, the total latency difference between well-implemented devices at these two rates is small relative to the human component of a reaction test result.
5. Do mechanical keyboards improve reaction time?
Mechanical keyboards can offer lower input latency than some membrane alternatives, depending on the specific products being compared. They do not improve the neural processing component of reaction time. The hardware delay reduction is real but small relative to human processing speed.
6. What is debounce delay?
Debounce delay is the time a keyboard firmware waits after detecting a switch transition to confirm the press is genuine and not electrical noise from contact bounce. Different keyboards implement debounce differently. More aggressive debounce settings introduce more intentional delay; lower debounce settings reduce that delay but require cleaner switch behavior.
7. Does rapid trigger improve reaction speed?
Rapid trigger improves key re-registration speed during repeated movement inputs. It can benefit counter-strafing, repeated directional changes, and rhythm game patterns. It does not affect the brain's speed at detecting and reacting to a visual stimulus on a simple single-press reaction test.
8. Does monitor refresh rate affect keyboard reaction tests?
Yes. A higher refresh rate reduces the average frame-timing delay before a stimulus appears on screen. This produces a slightly lower and less variable stimulus presentation delay, which can influence test results ā particularly averages across many trials. It does not change neural reaction speed.
9. Why does my keyboard reaction time change between attempts?
Trial-to-trial variability is normal and expected. Attention fluctuates. Anticipation can speed or slow a result. The display refresh cycle creates variable stimulus timing. Brief distractions, muscle tension, and fatigue all contribute. This is why averages over many trials are more meaningful than individual results.
10. How can I improve my key press reaction speed?
Practice randomized-cue reaction drills, avoid predicting stimulus timing, maintain consistent finger positioning, improve sleep quality, reduce system latency where possible, and track your average over multiple sessions rather than chasing a single fast score. Task-specific practice for your actual use case ā gaming genre, instrument, or task type ā transfers better than abstract drills.
Test Your Reaction Speed
Hardware is only one part of the response chain. Understanding your keyboard's latency, your display's refresh rate, and the full measurement chain helps you interpret results correctly. But the most useful thing you can do is actually measure your own performance across repeated attempts.
Take the test multiple times. Track your average. Establish a personal baseline you can reference consistently over time. That number ā your own consistent average on your own setup ā is the most meaningful data point you can collect.
