I guess there are many ideas +) another way to look at it would be this...
You have your convergences staggered, as you boom in on the bogey's 6, you open fire the first set gets into convergence and passes through, the second set now moves into convergence and passes thru
You set all guns to same point, you come in on bogey's 6 movin at a good speed you open fire outside convergence, you close to convergence, and then are able to walk all 8 converged guns down the length of the badguy doin max damage..
I used to use staggered, nowadays I like em all together, plus it means when i look thru my site and put the dot on the con at 350, I know all guns will hit that point. When staggered and u see that con at 350, some of your guns may shoot hi or lo depending on your convergence setting.
