How do you size a player to a specific bat size?

Thanks for the great feedback.

The 63-65 mph was with her hitting instructor at the batting cage where he works. He maxed the machine out to see if her hands were quick enough. They were.

I understood you to say there was a real live 14u girl throwing 63-65

my DD (12, almost 13. 5'2 124lbs) swung an end weighted 31/22(-9) all year long and struggled hitting all year. She changed to a 32/20(-12) for the tournament over the weekend (because it was cold) and hit the ball better than she did all year. several hits and alot of solid contact. I think the bat she used all year has better pop but may have been to heavy for her.
so i am looking to try to figure out if an evenly balanced -10 would be the logical choice?
