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.
