Each edge weighs one fighter’s offense against the other’s defense in this matchup, not each fighter vs the division in isolation — so a strong defense reduces (not erases) the opposing threat. Tap a row for the percentiles behind it. Thin samples are dimmed; too little data reads “not enough data.”

Per-tier records + bout-by-bout
| Tier | Jeisla Chaves | Yuneisy Duben |
|---|---|---|
| Unproven | — | 0-1 |
Schedule Score combines schedule strength (65%) with quality wins (35%). For fighters with limited UFC experience the headline is held toward a rookie baseline — a thin UFC résumé hasn’t yet proven a strong schedule — so debut and low-sample fighters read lower than established names. 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, and falls back to opponent UFC record-at-time for unranked opponents. UFC ranking data is sparse before December 2018, so legacy-era fighters score from record-at-time when ranks are missing.
Striking matchup
Where each fighter lands their strikes — and where each one gets hit — across head, body, and leg. Per 15 minutes of UFC fight time.

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
Wrestling output, ground threat, and control. Per 15 minutes of UFC fight time, with takedown defense as a percentage of opponent attempts stopped.

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.
Neither fighter has reached the third round in enough UFC bouts to read a reliable fade pattern — most of their fights end early. The round-by-round pace below is shown for what rounds there are.
Not enough shared rounds with per-round data to plot a comparable pace curve — at least one fighter rarely sees the later rounds.
Full per-round breakdown — both fighters
| Round | Fighter | Output / min | Sig landed / min | Sig absorbed / min | TD att / min | Control | Bouts |
|---|---|---|---|---|---|---|---|
| R1 | Jeisla Chaves | — | — | — | — | — | — |
| R1 | Yuneisy Duben | 8.4 | 8.4 | 10.2 | 0.00 | 0% | 1 |
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.
