Yeah WM the above spreadsheet might be all wrong. I'm working to redo it and everything else all over again right now.
Above: Take off is full ammo and normal fuel. (e.g. 2x20+2x30 and 50% fuel on 110). "Dogfight" is enough fuel for average dogfight to-and-back flight, and excess ammo thrown out (e.g. half the 20mm ammo on 110, but only ~25% of 20mm ammo removed on Ta 152)
I also didn't label measurement units.. It's a mess. I'm redoing everything.
