Women's Bantamweight · REAL v1.0 (registered) #12; v1.1 (shadow) #13

Descriptive profile. The resume rank is what has been earned; these statistics are context, not a prediction. A test on Oct 20, 2026 found that career statistics add nothing reliable to age, layoff and experience as predictors of the next result (experiments/REGISTER.md, EXP-2026-10-20-14).

Weight band 11-12: the 10th to 90th percentile of her position across weight vectors drawn near the 70/30 weights. Rating 1,585, deviation 123: measured from 13 UFC bouts; a one-bout newcomer sits near 290.

Age 31 (born 1994-12-30) · Height 5 ft 5 in (165 cm) · Reach 67 in (170 cm) · Stance Orthodox · 134 days since last bout (2026-06-20) · Last five 2-3 · Streak L1

Why she is ranked here

Rating 1,585 is the division's 9th highest of 24 board fighters; the ledger stands at +0.4 (+1.9 from quality wins, +0.5 from close losses to top-5 fighters, less 1.0 for blowout losses, less 1.0 for other losses outside the top 5; losses count for three years); 4 quality wins in 15 years, 1 over top-10 opponents; form penalty 0.15 for a 2-3 last five. Score -0.06 = +0.07 (rating term, 70% weight) +0.02 (ledger term, 30% weight) -0.15 (form penalty); score order put her at #12.

Opp. official rank = the UFC media-panel rank of the opponent on the date (C champion, #1 to #15, unranked; n/a before Feb 2013 or where no official board existed). Model p = the predictive model's pre-fight win chance for her (frozen performance-adjusted Elo; bouts before 2020 were in its tuning sample). Linked opponents have a profile.

Rating after each UFC bout from the frozen predictive model (performance-adjusted Elo, data/processed/elo_history.csv; a debut starts at 1,500). The resume rating's history is not stored, so this is the predictive line, which is a different number from the resume rating in the header.

Each dot is one decided UFC bout at her age then: the performance score minus the rating's expectation, on the score's own scale from -1 to +1 (filled = win, hollow = loss; above zero is better than the rating implied; a finish as a slight favourite is about +0.45). The dashed line is the population curve for all fighters; the solid line is this fighter's own fitted level and trend as of the data date, weighted toward recent bouts. One unit sustained over many bouts corresponds to about 695 rating points; a single bout's residual is noisy.

Held-out evidence (walk-forward 2016 to 2026, EXP-2026-10-21-01): the age curve held in every test year; the individual component is a weak signal (correlation 0.06 with the next bout's residual; among fighters aged 33 or over, the lowest predicted quartile won 38% of next bouts against 53% expected, the highest 48% against 52%) and adds nothing to bout prediction beyond the shadow model. No board uses any of it: the rankings answer who has earned the place, not who wins next (EXP-2026-10-20-09). Method: src/mmalab/decline.py; settings: config/decline.yaml (expectation from the resume rating; one unit of residual is about 695 rating points).
