I remember one crazy tater shot I hit on you mtnman, it was from the side, you were going about 400 maybe a 70 degree crossing shot but you were never looking at me. My entire focus was on an imaginery line way out in front of your line of action and hoping I lined it up correctly.
Ha! I remember that! Not like I could forget it, lol...
I'd be willing to bet though, that your strategy for the most part is to line up on a point in front of your target, relax on the controls, and fire a short burst a tad early? If it misses, set it up again? Rather than firing on a curving turn, you're flying more of a "stop-sign" circle, firing on the "flats"? Pull, relax, fire, pull, relax, fire?
In effect, that's treating the guns almost like single-shot weapons, even though we benefit from the "stream" aspect, which can correct for miss-judged timing?
That's basically what I do... There are times when I'll pull hard and squeeze, but for those I'm sure of a hit, and I know it. Close in, slow target (even if it's crossing) and I can hit it even if I'm blacked-out.
Now, on sustained lead shots, I'd guess you'll hose 'em down too (or walk your rounds on target), but I'd wager you don't often fire sustained bursts while holding much pressure on the elevator?
The reason I ask is because what so many seem to do is think there's a "magic" convergence setting, that makes up for "something", and they experiment looking for it thinking when they find it it'll solve their gunnery qualms.
I'd guess most of the better shots in the game don't screw around with it much though. They rely on a (or a few) simple technique(s) to score hits, rather than looking for a magic setting.
