Accuracy

A scoring pass is recorded before a gameweek, with the weights and coverage that were live at the time — a score is only interpretable next to the formula that produced it, and that formula changes as coverage improves. Once FPL marks the gameweek checked, what every player actually scored is attached to that run and never revised. Composite is the rank correlation between the model's score and actual points; naive is the same for FPL's own expected points alone. Lift is the average points of the top score band minus the bottom. Rows are written only by a scheduled call with a shared secret; this page reads them.
