John you are the freakin MAN! I hadn't even considered making an excel sheet of it for fear of being ridiculed.
Kick: Pitcher stamina has to do with the arm holding out over the course of a game (starting pitcher I mean). Throwing 100 pitches requires upper body stamina / good conditioning of those muscles and tendons. The catcher stamina comes from having to squat for the better part of four hours, although those calf pad things they have now probably makes it much easier on their back and legs.
You're right though; I thought about those two ratings specifically a couple of times. I was trying to be fair since there are different kinds of stamina. A track and field guy might have tremendous cardiovascular stamina and not be able to throw 20 hard pitches without getting jell-O arm, and conversely the pitcher might run to third on a rare triple and need an oxygen tank.
