Practice F1 Starts Without False Starts

Updated 2026-08-10·By ReactionF1 Team

All guides·Methodology

Goal Shift

First target: five clean starts in a row. Speed is secondary until the jump rate drops.

Drill A — Silence the Wind-Up

Hands ready, shoulders soft. If you feel a countdown in your head during the hold, abort and restart. The hold is supposed to feel uncomfortable.

Drill B — Zero-Jump Sets

Count only clean attempts. Any false start resets the set to zero. Short sessions beat long frustrated ones.

Drill C — Speed After Clean

Only after a zero-jump set, allow one speed set where you chase best clean ms without letting jumps creep back.

Logging

Track false-start rate beside best clean time. A slower clean week with fewer jumps is progress.

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.
