Reaction Time Statistics:

Here are some interesting statistics from the Reaction Time database.
These change in real time, as more people take the test.

The average (median) reaction time is 215 milliseconds.
I've recorded 2201227 clicks so far.

Overall Distribution of Reaction Times:

You can clearly see a nice bell curve here, peaking around 200 milliseconds.

At about 120 ms, it becomes apparent that most of these clicks are the result of clicking too soon, and just getting lucky. Otherwise, you might see a smoother ramp from 0 to 130, but it seems to just be noise.

The cutoff for leaderboard scores used to be 130, but some of the fastest 99.9 percentile of players on the site complained, pointing out how often they got legitimate scores in that range. Now it's 100 ms.
