Coach...And there is one of your best points..
Nothing will get a new shooter-young or old-breaking more targets consistently than a good coach..Not 2inch extended chokes, not even the newest gun for the game..A good coach starts one out with the fundamentals of how to hit, and without a solid foundation consistency will always be the Dog chasing its tail. A really good coach will make stock adjustments on the fly. A good coach will read your breaks in the sky and tell you how your pattern is for the game you are playing. A good coach will tell you how to use your eyes to the best advantage. Something most never figure out on their own.
I never have a kid shoot the pattern plate, never look down their rib to check their gun-fit, and never give them an eye-dominance test. If they have an issue with any of those things, I will quickly see it, as you say, "on the fly."
I tell them to put in one choke (two in an O/U, of course) and never change them. It is not that those chokes are always ideal, it is just that I don't want the kid thinking the path to higher scores is through gadgetry. I want them thinking the ONLY path to success is thru perfecting what THEY do.
It has worked well so far.
Oh, and check your PM's! I sent you a video to watch.
