Since you mentioned it.. Allied pilots, in DCS, are used to 'spray and pray' tactics from a mile behind the target, due to the 'paper plane' feeling of the german planes (bad damage model?? :/), that is, 1 hit engine dead, 1 hit wiggling, 1 hit from 6 o'clock pilot dead and so on. On the other hand, to be efficient in german planes you have to shoot the target from less than 100m, and from high deflection positions. Indeed, the 3cm is way under performing and that must be tackled correctly by ED in the new DM.
