Just a quick update for the Position Adjusted XRAPM stuff I've been doing. I decided to switch from my earlier 3-Position system (Bigs, Wings, Guards) to the traditional 5-Position system.
This was my original goal, but for some reason I couldn't get any respectable correlations with winning percentage or original XRAPM, when utilizing the 5-Position adjustment. That is, until quite recently, which is why I'm making the changeover.

Original XRAPM - Position Adjusted XRAPM Correlation
Original XRAPM - Winning % and Efficiency Correlation
Adjusted XRAPM - Winning % and Efficiency Correlation
There was a sizeable drop between the 3-Position/Original XRAPM Correlation (93%), and the new 5-Position/Original XRAPM Correlation (84%). As depicted by the first table, this is almost entirely due to the decreased D-XRAPM Correlations to each other. I can't complain, as that was the original goal.
What's impressive however, is how well the new 5-man Position Adjusted XRAPM Correlates to Winning Percentage, Offensive, and Defensive Efficiencies. There isn't much drop-off, either compared to the Original or 3-Position XRAPM. In fact, the new 5-Position XRAPM has a stronger correlation to defense (89%), then the earlier 3-Position XRAPM (84%).
I'll be posting the new 5-man Position Adjusted XRAPM numbers for the top 30 under the same tab at the left.
