Why it works
Simple reaction time is one of the oldest measures in experimental psychology and a favorite of gamers and athletes. The median human clocks in around 270 milliseconds — most of it is signal travel time, but staying relaxed and truly ready shaves off real milliseconds.
FAQ
What is an average reaction time?
Around 250–300ms for a visual signal on a screen. Under 230ms is elite territory; touchscreen latency adds a bit for everyone.
Can I actually get faster?
Your nerve speed is fixed, but focus, posture and anticipation are trainable — most people improve 20–40ms with practice.
