Babs,
This isnt quite right,at 425 conv anything less than that distance the round will be low,check Bustr's tables,the round only rises to the pipper at conv distance,it doesnt fly above and drop down into the pipper like shooting in RL. If this convergence range works for you great but your discription of the flight path of the bullet is not right.
You can easily check this with the dot target,set to 200 and see where your rounds land,I'm betting they will be slightly low until you push the target out to conv. distance and then drop off once past the conv. distance.
Bustr's data (and your post) is spot on, after payign closer attention to how it's workign these days. So then I was wondering why I think it's chucked high, but otherwise I definetley still like 425 because it stays pretty flat all the way out there.
As to the illusion of it being chucked high, If Im pulling back on the stick in a tight turn, and make a near dead-distance snap shot on a target passing under my nose to above it or some similar pass, the delay/lag in the HE detonating and damage being displayed on the target gives almost a near-perfect illusion to being pitched relatively high to your LoS at a near-dead distance.
More fun was getting so close to one target a night or two ago, squezing a burst of taters, and instantaneously killing the target while hiting my oil, killing my engine, and breaking my radiator. Aparently the target was inside my hollow propeller shaft, and I blew off the front half of my engine.
