Net rating per 100 possessions, Regular Season.
All 30 teams, nine full seasons of lineup data.
We built our own EPM-family metric.
IPM is the RAPM we compute from reconstructed play-by-play, re-fit to shrink every player toward a box-score prior trained on nine seasons of our own data. Stable and current at once.
Tested before it shipped
For every season since 2017-18 we froze the metric on part of the data and made it predict games it had never seen, against pure RAPM, the box prior alone, and a league-average baseline.
17/17
held-out tests where IPM had the lowest prediction error
9
seasons of self-computed RAPM behind the prior
