Its the same ranges as previous CODs. 1 is still 1 ....but now 1.5 sens is 2 ...and 2 is 3 sens... 2.5 is 4 sens and so on they made it so you could find the the inbetweens of older sensitivities if a 5 was a little too slow and 6 was a little too fast and you could select a 5.5 ... now you can. Get it?
anything above a 12 is going to be for people using Kontrol Freaks ... as they offer long sticks to fine aim
