Power Index (TOSS model) = 50% APR + 50% FQI. FQI (Flight Quality Index) = per-match flight performance scaled by opponent strength, averaged across dual matches. Hover for FQI+ (100 = classification average). How does this work? →

New from 2026-04-26: the primary Power Index is TOSS — APR is unchanged, and the flight component is FQI (each match's flight performance scaled by the opponent's APR, unclamped, median-normalized). The previous RPI-based formula is retained as Legacy, and QWS (ITA-style quality-weighted wins) continues as the experimental comparison model. Use the Model selector above to switch views.
