R3 pace · 3 bouts

O'Brien holds steady (-1% per round through round 3). Within fights that reached round 3, O'Brien keeps 91% of round-1 output by round 3 (3 bouts).

O'Brien — HOLDSOutput / min

Rounds backed by fewer than 2 bouts are drawn smaller and dimmed with an n= count — a deep round seen in one or two fights is a thin sample, not a settled rate. Per-round bout counts are in the breakdown below.

Full per-round breakdown

What drives the pace · per round

The composite output line above blends these three inputs — splitting them out shows whether the work rate is built on striking volume, takedown pressure, or top control, and which input fades.

Output / minis the headline work rate — significant strikes landed, plus 3 per takedown attempt, plus one per 15 seconds of control — so a takedown-and-grind round isn’t scored as idle the way bare striking volume would. The remaining columns are its components. Per-round rates use UFCStats per-round data (available for ~95% of bouts since 2008). Each round’s rates are averaged only over bouts that reached that round, so the bout count shrinks as rounds deepen. The final round of a finished fight is pro-rated by its actual length.

Per-bout quality scoring: champion = 100; same-division ranks 1–5 = 90 → 78 linear; ranks 6–15 = 75 → 60 linear; cross-division champion = 78; cross-division ranked = 45; title-fight challenger (no rank signal) = 50, bumped to 65 when opp had an elite career UFC record at the time. Unranked opponents are scored on UFC record-at-time (long-tenured vet 60, contender-level 45, established 30, building 18, unproven 8). P4P top-10 at time adds +5; top-3 adds +8 (capped at 100). The Schedule Score combines schedule strength (65%) and quality wins (35%), then is held toward a rookie baseline for fighters with limited UFC experience so a thin résumé reads honestly low.
