http://www.humanbenchmark.com/tests/reactiontime I've been playing on this the past few days and its addictive. I can get an average of 1.8 on a good run, my fastest ever single was 1.56. I've actually improved since when I first found it from about an average of 2.2, I've just gotten better from training, and also finding the right place on the mouse to click shaved a bit off too! I want to get it down to a 1.4, I can feel there's room for improvement in there! What can you get?
