Frequently Asked Questions

What is an average human reaction time?

The average human visual reaction time is around 200–250 milliseconds. Top gamers and athletes can achieve 150–180ms, while times above 300ms are considered slower than average.

Does caffeine or fatigue affect reaction time?

Yes. Fatigue, alcohol, and certain medications slow reaction time, while moderate caffeine intake can improve alertness and slightly reduce reaction time.

How many rounds should I test for an accurate average?

Run at least 5–10 rounds and use the average result, as individual attempts can vary due to anticipation, distraction, or clicking technique.
