I really like the idea but it&#x27;s completely off. What it should do is measure your reaction time: the time between the sign appearing on screen and the user pressing the mouse or tapping the screen. What it does is include frame rendering time. I apparently have the reaction speed of a 80-year-old at 22 (900ms), while I&#x27;m sure my reaction time on computers is around 225ms (measured on different occasions).<p>Also, you compare with the average, but what&#x27;s your error margin? Were there 25 year olds that got 350ms and 200ms or did everyone consistently get between, say, 240 and 250?
