Start with a baseline
Before you change anything, run the test above three times and note the average in the Your scores panel. Each run is five tries, so three runs give fifteen measurements. Without a baseline you cannot tell a real improvement from a lucky day.
Steps that improve reaction time
- Sleep properly. Sleep loss slows reactions and makes them less consistent. No drill makes up for a bad night.
- Warm up. Two or three runs before the one that counts wake up your attention and your hand.
- Rest your finger on the button. Keep it touching and relaxed. A tense hand moves slower.
- React, do not predict. The wait before green is random, about 1.5 to 5 seconds. Guessing leads to early clicks, and an early click only repeats the try.
- Practice in short sessions. A few runs on most days is enough. Practice mainly improves consistency by trimming your slow tries.
- Use caffeine sensibly. A moderate dose gives a small improvement.
Fix the hardware
Part of your score is not you. Screens and input devices typically add 20 to 50 ms to an online result, and you can remove some of that.
| Change | Why it helps |
|---|---|
| 60 Hz monitor to 144 Hz | A new frame every 6.9 ms instead of every 16.7 ms |
| TV to monitor, or game mode on | Less image processing before the picture appears |
| Wireless mouse to wired | Removes one possible source of input delay |
A hardware change lowers the number on screen without making you any faster.
What realistic gains look like
Expect tens of milliseconds, not hundreds. The speed of your nerves does not change much with training. What changes is how often you produce a slow try, so your average tightens and drops a little.
Age sets a soft limit too. Speed peaks in the early to mid twenties and declines slowly afterwards, though experience makes up for a lot of it.
A sensible goal is to move up one band. If your average sits in the 260 to 299 ms range, getting under 260 ms with good sleep, a warm-up and better hardware is realistic. Getting under 200 ms is exceptional for anyone.
