Where he stands
Sergio Pettis is 6-4 across 10 fights on our tape. Our rating has him at 1566 — it moves with every result and weights who he beat, so a win over a ranked opponent counts for far more than one over a debutant. A record on its own says very little in this sport — two fighters at 12-3 can have faced completely different opposition, which is exactly the gap the rating is built to close.
He goes the distance
Sergio rarely finishes — most of his wins come on the cards. That's not a criticism; decision fighters are often the most predictable profile on a board, because they win by accumulating rather than by landing one shot. It does mean his ceiling in any single fight is capped, and that the judges become a variable no model handles well.
How the model reads him
Sergio's rating updates after every result and weights the quality of the opponent. Against a specific opponent it becomes a win probability, adjusted for the stylistic matchup — striking output against absorption, takedown rate against takedown defense — plus age and layoff. The weighting is ours; the output is published on the fight board and graded.
What we'd flag
The tape starts in 2015 and covers UFC and Contender Series only, so career records elsewhere aren't reflected. Beyond that: MMA has the highest single-event variance of anything we model, and no rating survives contact with a flush shot.
