Test your reaction speed.

.231 is my best. I'm slow.

I'll write a bot for this and beat everyone.

heres the trick:

clcik start.........then click stop but dont let go off the mouse button........as soon as it changes release the mouse button.......

I click on the stop and move my mouse off of it...then use Enter. Either way I can't beat .15

To get those fast times, you need to just guess lucky. It is impossible to have a human reaction time that fast when adjusting to color, such as this.

I don't have the athletic ability required for physical activities.
