Reaction Time Results: Build a Fair Baseline

What the milliseconds include

This result measures elapsed browser time from the visual change to the recorded click. It includes display refresh, browser scheduling, visual detection, decision, movement, and device input, so it is not a direct measurement of one biological process.

A number from a sound test, laboratory device, phone, or another website is not interchangeable with this one. Build a baseline on the same hardware and browser before interpreting a change.

What counts as improvement here

The site has no representative dataset for labeling a score normal, fast, or exceptional. Improvement means a lower repeatable average on the same setup without more false starts, supported by several runs rather than one unusually quick click.

• Complete all five valid rounds; false starts do not count.
• Use the run average as the main score and the spread as consistency context.
• Take three runs and compare their median with a later three-run session.
• Keep the device, browser, input method, and finger position constant.

Do not infer age or health

This game does not collect age, health, medication, impairment, or representative population data. A browser result cannot place you in an age band or explain why one session differed from another.

Use it as a narrow self-tracking task. Seek an appropriate professional assessment if your concern is medical, occupational, or safety-critical; this score is not designed for those decisions.

Control the setup

Screen refresh, browser load, input device, posture, and finger travel can all alter the recorded path. Keep them fixed when comparing sessions and note any change rather than guessing its size.

If you want to compare two devices, alternate runs between them and repeat the pair several times. That design separates the device question from a simple warm-up effect better than one run on each.

Measure yours

Five valid rounds produce the displayed average, while the difference between fastest and slowest gives a within-run spread. Three complete runs on one setup make a more useful baseline than one run; repeat that procedure later and compare the medians.
