You know, I used to use a longer, staggered convergence, but no longer. I found with the staggered convergences I was an assist machine. With all convergences set to one point, I get more kills then a spread setup.
While I can theoretically see why the staggered plan that Fariz illustrates above makes sense (I used and reccomended it in the past); it just never paid off for me flying the Jug. I am back to all guns at 325 in the P-47, and 300 for the F6F5. I find that my snapshots pay off much more with this setting than they used to with the staggered convergences. I fly the Jug as an E fighter primarily, but of course do some BnZ. With all guns at 325 I'm quite effective between about 250 and 450, and that's where I get the majority of my shots. Cross my guns in the 300 range and a snap shot is all I need. It doesn't always work, but it makes enough of a difference to make the snap shot workable in the Hellcat with 6 x.50's, where it is less viable with spread convergence.
Try 'em both, and pick the one that works better for you.

I am a really crappy shot, so those of you with better gunnery may get different results.
