Warm-Up & Tracking Progress
Updated 2026-08-10·By ReactionF1 Team
Warm-Up Without Noise
Two or three easy lights-out starts to settle input and attention. Do not count warm-ups in your official median unless you decide to — just be consistent.
Best-of-5 Clean
Five clean attempts. Record best and median. Ignore false starts for the speed stats; still count them for jump rate.
Outliers
If one attempt is wildly slow because you looked away, discard it and note why. Do not discard inconveniently fast times without a false-start reason.
Same-Device Rule
Progress is a week-to-week story on one setup. Switching phones mid-log resets the plot.
Score Bands
Use ReactionF1 educational bands as language, not law. Pair them with your jump rate so “faster” does not mean “earlier.”

Frequently Asked Questions
A couple of attempts — not a second full session.
Both: best shows peak; median shows repeatability.
Stop early. Tired practice teaches bad timing.

Methodology & Timing
Our reaction time test uses performance.now() for millisecond-precision timing. The stimulus (lights out) and your tap are both timestamped in the browser. Your reaction time is the difference—typically within ±5 ms of true response time, depending on device and display latency.
Device latency and browser variance affect results. A 60Hz display adds up to ~16ms of delay; touch and mouse input lag also contribute. For a detailed explanation, see our device latency & reaction time guide.
