Here's some Giant Squid to tangle with.
Question to ponder: Why does the real world MK108 drop from 0 elevation in negative numbers as tested locked into the engine hollow shaft but, our game numbers from a level engine go from a negative up to a postive then back to a negative? The reason the 50 yard drop numbers are different between the 152 and K4 is the 152 pilot sits higher from the engine line than the K4 pilot. The 152 MK108 is shooting up to 150 from a lower position than the K4's.
You guys are getting shafted by the dispersion while being handed a favor on the drop so the code is kept the same across all fighters for gunnery. Don't fix whats not broken if it works over a cosmetic issue probably.
Your real problem is the crap shoot randomised dispersion pattern past 100 yards in the game. Whatever game world angle(convergence) you tip your MK108 barrel up to, the dispersion stays the same. You just have a kinda sorta level but ever expanding shotgun pattern cone out to 400 yards. Use 200 as your convergence and it just about evens out the cone all the way to 400. It's between you and Hitech if you think his 24 sided randomiser dice is loaded.
Too bad you guys don't have a G10 with the MG151\20 in the nose. Much kinder dispersion out to 400 with the MG131's.
