How these scores are calculated
Fight IQ = 40% striking-accuracy percentile + 30% striking-defense percentile + 30% takedown-defense percentile within the division.
Requires 3 UFC bouts, 15 measured minutes, at least 10 division peers, 100 strike attempts, 100 opponent strike attempts and 10 opponent takedown attempts.
Cardio = 100 × the median late/early significant-strike attempt rate ratio, capped at 100. Compare rounds 3+ with rounds 1–2 within each bout. Requires 3 eligible bouts with at least 60 late-round seconds each. 100 means maintained or higher late pace.
Fight IQ summarizes accuracy and defense; cardio summarizes retained pace. Style, opponents and grappling affect both. These scores do not measure intelligence, physical fitness or win probability.
