Doh, you're right, merged them now The vehicle calculations are just for the tank driver, the gunner use almost the same sensitivity as infantry (an update with precise calculations is coming). Since the the main turret have a maximum speed/acceleration, it will feel sluggish (intentional and by design obviously) and actual distance/360 will vary depening on your DPI settings and how fast you move your mouse. You need to move your mouse very slowly to get the calculated distance. It will only turn about half way around if you move your mouse quickly over the calculated distance.
