01Recent games matter more
Exploratory historical tuning selected a 240-day half-life. The live cohorts will test whether that choice holds up.
02History and age stabilize the answer
The model blends the current season with longer-term performance and the normal way players change as they age.
03Context had to earn its place
In exploratory historical comparisons, opponent, rest, team-change, and injury-return inputs did not improve the selected error score. They remain outside the live candidate.
04Lineup evidence comes later
This version excludes teammate and opponent lineup effects. Those inputs can be tested only after the live 20- and 40-appearance checkpoints.
Research preview—not the live Impact Rate.
