Aim LOW at 200M for maximum concentration of fire. You will still have difficulty with different impact points for deflection shooting, due to different MG and cannon projectile velocity.

Aim dead on for targets at 400M, but notice serious 4.5M DIVERGENCE of cannon at 400M. Almost a waste of time using cannon at 400+, unless you are attacking BIG targets, or kick the rudder left and right.

At 300M MG and cannon still shoot higher than gunsight aimpoint. Also MG and cannon have neither verticle or horizontal convergence relative to aimpoint, but offers a 'spray' concentration of fire. Would be damn near impossible to be able to get combined MG and cannon deflection shots.

No wonder the pilots who got the most kills were also the ones that said get in real close.

P.S. Love the diagram.
