How your result compares
The human bands are descriptive, not percentiles or medical labels. Browser and device latency remain in your score.
Reference notes: a calibrated study observed a 231 ms mean; star-nosed moles averaged about 227 ms in a tactile prey-handling task. A fruit fly can start an automatic escape movement in about 3.4 ms, illustrating why animal reflexes and deliberate human clicks are not directly comparable. Human study · Mole review · Fly study
Consistency describes the range of this session only. It is not a percentile or comparison with professional players.
Why use a 10-round reaction speed test?
A longer session shows more of your trial-to-trial variation than a single fastest click. The headline score is the median of ten valid rounds. We also show the average, best, worst, and spread so one unusually slow round is visible without dominating the interpretation.
This page is designed as a sprint challenge, while the homepage uses a shorter five-round baseline. Use the same display, browser, and input device when comparing sessions.
How to get a comparable result
Keep hardware fixed
A different monitor, mouse, touchscreen, or Bluetooth connection can move the measured time.
Finish all ten rounds
Do not discard slow trials simply because they make the result look worse.
Compare medians
The median is less sensitive to one unusually high or low value than the average.
