A career line lumps every year together, and a fighter’s 2014 does not describe his 2026. Each year here is the same count over that year’s fights alone, with its own minutes, so it can be read against the career line beneath it.

Round length is read from each fight’s round format, so a 12-minute opening round from 1995 counts its twelve minutes. A round is counted only for the fights that reached it; the first column is the denominator for the rest of the row.

UFC bouts only, counted from the fight rows; the promotion’s listed pro record above covers every promotion and is a different denominator. Volume is per minute of cage time and accuracy per attempt; how he finishes is counted in his wins, the one place a fight is the unit. Significant strikes only. Control time the source did not record is absent, never 0:00.
