I guess you have never flown in the early war arena or mid war arean. lots of HO's in both and the numbers are the numbers you suggest for the perfect gamming experience. People HO, why not. Someone turns in at you and because your head on, you don't pull the trigger? who you kidding?
If it's a 1-on-1 even fight, I will generally try to gauge the other guys intentions. If it looks like he's going to fly by (i.e. he doesn't keep making small adjustments to re-aim his nose at my face) I generally won't shoot. If he does, I'll either shoot back (again, spite) or start my turn.
If I make an H2H pass and I do get killed for my poor judgement, it's my own damn fault. I may get a bit angry but... *shrug*
If I change course and he still puts 2 in my head, hey, nice shot. If I did my job properly it would have been a hell of an angle.
