0.2m/s can't be right, I assume you're estimating that? I mean, I can easily flick my mouse at >3m/s according to mousetester. Average tracking speed is another thing but I feel you should use the max speed you're able to consistently reach since that's what you theoretically would use when reacting to an enemy behind you, no? Now I'm not saying I'm constantly reaching 3m/s while gaming but it does make more sense to me to use that since I realistically could reach that if I happened to get caught off guard or something like that. I wonder if there's some software that measures tracking speed continuously that I could use to monitor my in game mouse movements, all the programs I have only measure when holding a button?
