All figures are 0–100 ratings (shown as %), not percentages of anything literal. Schedule strength = the average quality of every UFC opponent faced (win or lose). Win quality = the average quality of the opponents actually beaten. The composite Schedule Score combines schedule strength (65%) with win quality (35%). Per-bout opponent quality is scored on rank-at-time-of-fight (champion 100, ranks 1–5 = 90→78, ranks 6–15 = 75→60), with cross-division and P4P signals layered on, falling back to opponent UFC record-at-time for unranked opponents. For fighters with limited UFC experience the headline is held toward a rookie baseline, so debut / low-sample fighters read lower than established names. UFC ranking data is sparse before December 2018, so legacy-era fighters score from record-at-time when ranks are missing.
Career splits
Striking matchup
Each fighter's offense mapped against the other's defense — where one attacks meets where the other gets hit, across head, body, and leg. Per 15 minutes of UFC fight time.
Duncan has the striking edge (+18).

Each lane: the attacker’s strike rate (offense) vs the other’s rate absorbed (defense), graded on the division. The bar leans toward whoever wins the exchange — longer + greener = a bigger, higher-quality edge.

Per-15-minute rates are sourced from UFCStats fight totals across each fighter’s UFC career. Division percentile is computed against every UFC fighter who has competed in this weight class with at least two recorded bouts. Lower “absorbed” values are better — the percentile is inverted so “top of division” always means better outcome.
Grappling matchup
Takedowns, submission threat, and control. Per 15 minutes of UFC fight time, with takedown defense as a percentage of opponent attempts stopped.
Each metric graded on the division — the bar leans toward whoever wins that part of the grappling exchange (longer + greener = a bigger edge).
Allen has the grappling edge (+19).

All rates computed from UFCStats fight totals across each fighter’s UFC career. Takedown defense = opponent attempts stopped ÷ opponent total attempts. Control time figures are minutes the fighter spent in a dominant position per 15 minutes of fight time. Accuracy under 8 career attempts is shown raw and ungraded — too small a sample to rate against the division.

Pace & fade
How each fighter's work rate holds up as a fight wears on — round-by-round output (striking, takedown attempts, and control time combined), and whether they fade. The fade % compares round-3 output to round 1 over bouts that reached the third round.
Cardio edge to Allen: Allen holds steady (+2% per round through round 3) while Duncan fades (-14% per round through round 3). Within fights that reached round 3, Allen lifts to 114% of round-1 output by round 3, Duncan 89%.
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.

What drives the pace · per round
The composite output line above blends these three inputs. Splitting them out shows whether a fighter’s 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 — a 2:30 stoppage counts as 2.5 minutes, not five — so an early finish doesn’t distort the per-minute pace.
