So, how do you measure it? I've puretrak talent and from side to side it takes about 3,5 times to make full turn in game, aka 360.

This makes my 360/cm something like over 100cm. And you are saying 50cm is low sensitivity, and some absurd mofos play like with 60-70 which is absolutely unplayable? Da faq im reading. Am I doing this rite? I think this mousepad is something like 45-48cm from side to side, and in game this movement means about 120 degree turn.
