Glad that worked out for you. I was definitely in the too-much-ain't-enough category for a long time, so I know easy it is to get locked into the idea that if 200 rounds is good, then 500 is better.
I also learned to schedule workouts with exercises that require a lot of grip strength (farmer's walks, chin-ups, deadlifts, etc) for AFTER range sessions, ideally on the following day. My hands and forearms need time to bounce back from that kind of work. Like Pat McNamara points out, there's no such thing as overtraining, but there is such a thing as under-recovering.
