The only thing I didn't understand with the calculation is "The hipfire look, ADS and Scope.
So, here is my calculation for the last 3 years :S
Kinda close
Mouse Sensitivity 3.68
Monitor Distance Coefficient 1.78
Vertical Sensitivity Multiplier 1.00
ADS Horz. Sens. Multiplier (Low Zoom) 1.06
ADS Vert. Sens. Multiplier (Low Zoom) 1.06
ADS Horz. Sens. Multiplier (High Zoom) 0.85
ADS Vert. Sens. Multiplier (High Zoom) 0.85
