it looks to me from that diagram, the 200m horizontal setting for the cannons is too far? the vertical intersect and los per diagram is guesstimate at 150m. so if you want to use the pip, i think you would back down the horizontal setting of the cannon ammo to same (i.e., 150m). so its a matter of adjusting the convergences to the aero properties of the ammo if you want to use the pip, i guess.
