Field notes
The model is described as trained on NBA seasons 2016–17 through 2022–23 and tested on two later seasons it says it had not seen, covering 2,151 games. The page says its player adjustment helps most when one of the three players with the most minutes is unavailable; for low-impact substitutes it displays approximately zero, while acknowledging that the direction of each substitute’s effect has not been measured.
