Assessment notes
Rank is ordered by Prospect Score, the model's 1-100 composite score. Median outcome is only one input; performance, track record, age-to-level context, high outcome, confidence, and risk also affect rank. This player can rank below a lower-median player when risk, confidence, current performance, or age-to-level context pull the composite down
