idea: do a match and after get a "sensitivity" that maximazes your accuracy.

i checked code of AC ...
sqrt(dx*dx + dy*dy) * dx * 1/t * a/v * c = dphi

phi = yaw or pitch
a = mouseaccel
v = sensitivity
c = constants

sqrt(dx*dx + dy*dy) * 1/t - the length of vector in time unit
dx - move in x direction
dy - move in y direction
a ~ influence dx or dy
v ~ influence time unit ~ since vector unit

correct me if i am wrong ..
