Honest, sourced explainers behind the scores — what the numbers mean, how devices change them, and how to actually get faster.
The average human reaction time is about 273 ms. Under 250 ms is good, under 200 ms is excellent — here is the full scale, and why your device changes the number.
Reaction time slows with age — lab studies say about 0.55 ms per year, browser data suggests more. What to expect at your age, and what actually moves the number.
Consistent training shaves 20–40 ms. Sleep, warm-ups, focus and hardware do most of the work — supplements do not. A practical, honest playbook.
Phones add 35–140 ms of screen and touch delay. Which score should you trust, and how to compare fairly across devices.
You get better at the game itself — that part is certain. Whether it transfers to everything else is still argued. An honest read of the evidence.
