Re: What is your REACTION speed?
The fastest I got was 227 milliseconds, the slowest I got 320 milliseconds (technically the slowest was like 7 seconds but that was a goof). The most result seen was 280-ish milliseconds. I did way more than 5 tests. It sucks that this isn't necessarily as accurate as it could be due to the variability of the computer stats, or whatever.
A more fun game was for me to press the button as fast as I can until the light turned green, and see what I got. Pretty sure it had to do with some luck, but it was mostly consistent speed/stamina: 39 milliseconds.
