FAQ
What is a good reaction time?
Average is around 250ms. Under 200ms is excellent. World-class athletes hit 150ms. If you're at 300ms+, consistent daily training will improve it.
Does caffeine improve reaction time?
Moderate caffeine (100–200mg) can improve reaction time by 10–20ms, but tolerance builds quickly and excess caffeine increases errors.
