Figjam=off, this is just a personal reply.
Sorry, I have to take exception to this one. I'll agree higher percentage probability, but I'm below 300 rpms and have 7, including one night back-to-back (3rd and 4th games, so it technically didn't "count" for b-2-b recognition and who knows what the next game would have been...). My brother is maybe 300 on a good day, and he has 13 bowling 1 night a week (he's kinda a natural, but I won't admit that...) . Man, I'd love to swing it, but that's not my game. Targeting hasn't been lost as a concept, and repitition is king.
It can be done, but everyone wants to hook it, so they don't bother with the details.
