If I'm not mistaken [URU]BlackFox actually posted Images with graphs of the real numbers.
If those numbers are correct (which I have to assume at this moment) the bullet of a MG151/20 in the wingroot of a FW190A aimed at a spot 550m away starts out about 120cm below the aiming line, crossing it for the first time at 135m distance, then actually climbs up to 84cm above the aiming line (2.04m traveld upwards) where it will be at around 350m distance, before falling back to the aiming line and meeting it a second time at 550m.
This numbers actually show that Herra Tohtoris simplified math isn't far off for (relative) short distances. However if the distance becomes longer the projectile becomes slower and the drag becomes less marginal.
