Here's another interesting table. It appears that players self adjust to approximately 40-50 point ranges between MPG / MG1, and MPM / MM1 in terms of where the peak numbers are located in the distributions. The broader distributions are likely due to regional differences where pros may still be 40-50 points on average above the ams everywhere but pros (and ams) in some regions are higher than similar age pros (and ams) in other regions.
