the problemis with most reaction tests though is that you know that your being tested and so your actual response time will be less then within a game, where you have to realise the situation then react accordingly, i dont think these tests can be accurate compared to a situational reaction time which is more real world and game world accurate, a good example is that on the NIA reaction time I scored a perfect zero (no joke), but thats because I was sat there and just guessed when the symbol was going to appear. Based on the physical mechanics of how your body moves and the speed in which a computer can read an electrical impulse then it will shave reaction times by the 60% it claims but thats just the maths talking, wether that actually translates into the real world is something to be seen.
