Just wanted to share this. I found it pretty interesting. There big shiny new stat is "CraftedPM" or Crafted Plus-Minus.
Here's the formula:
((standardizedRPM x 5) + (standardizedPIPM x 5) + (standardizedRaptor x 7) + standardizedBPM + standardizedMYRPM + standardizedMYPIPM + standardizedC20TPM + standardizedPredator + standardizedPPIPM + standardizedLARAPM + standardizedLA3RAPM) / 25
So as you can see they weight different RPM-based stats, add them up, and then divide them for an overall average of various stats.
The results are pretty interesting.
