Player Peak Performance Equation (Revised)

I've been playing with this peak performance concept for the last few days and added a few components (which I'll explain later on) and tweaked the values for some of the others a bit. It's still pretty rough, and it started out as a look at Yao Ming's career, so most of the players I've evaluated so far are centers. But I wanted to see how well it translated to other positions, so I threw in the rest of my current top 20 players and a couple players I was curious about, as well. (Also, don't worry, I haven't forgotten about the List of Greatness. I just need to get off my ass and type up the results.) Anyway, here's the quick and dirty results of my revised system:

Player Peak Performance Equation (Initial Results) - Updated with Stats

Here's the initial results with the Peak Performance Equation and the first 12 (okay, technically 13) players I've tested it with. I still have a bunch of other guys to throw in to the mix to fine tune it (pretty much everyone listed in the comments) but I wanted to get some initial reactions and feedback from my readers first.
