How consistent is your reaction time across multiple attempts?

Ever get one surprisingly fast reaction-time score, then fail to repeat it?

A single attempt can be misleading. Anticipation, practice, fatigue, your screen and your input device can all affect the result. Comparing several rounds on the same setup gives you more context than chasing one personal best.

Disclosure: I run VoltReflex, a free browser-based reaction-time test:
https://voltreflex.com/

It offers 5, 10 or 20 rounds with best and average scores, without a signup or download. It’s a casual personal benchmark—not a medical assessment or a precise hardware latency test.

I’m curious: when you repeat these tests, do your scores settle into a fairly narrow range, or jump around considerably?
