THE EXACT RULES
A session is 5 rounds. Each round waits a random 1200–4000 ms, turns green, then wants one press. FALSE START = a press while the pad is still waiting, or a press under 120 ms after green. A false start ends that round and fails the whole session — you cannot win one. A press over 3000 ms after green is a miss and also ends the round without a time. WIN = all 5 rounds record a time, with 0 false starts and 0 misses. Best-ever time and a rolling average of your last 10 session averages are kept in localStorage.
