I agree with the idea of less shooting more often, but I'd say for me 200 rounds would be "more shooting".
I'm fortunate in that I live in the woods and have my own range, but I find 30-45 rounds (2-3mags) 3-4 times a week is more than enough to both keep me sharp, and burn up my ammo budget.
First mag I usually shoot 5 round groups, and then I use the other 1-2 to shoot faster, at multiple targets, or anything else I'm itching to try.
I rarely shoot 200 rounds in a session, and I don;t know as I've ever shot 500. Maybe one or twice a a gravel pit.
