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 23-29: the 10th to 90th percentile of his position across weight vectors drawn near the 70/30 weights. Rating 1,545, deviation 292: measured from 1 UFC bout; a one-bout newcomer sits near 290. Provisional: 1 UFC bout; the rating rests on little evidence.

Age 27 (born 1998-12-02) · Height 5 ft 10 in (178 cm) · Reach 70 in (178 cm) · Stance Southpaw · 274 days since last bout (2026-01-31) · Last five 1-0 · Streak W1

Why he is ranked here

Rating 1,545 is the division's 38th highest of 94 board fighters; the ledger stands at +0.0 (no quality wins or recent losses on the ledger); 0 quality wins in 15 years, 0 over top-10 opponents; no form penalty (1-0 last five). Score +0.12 = +0.04 (rating term, 70% weight) +0.08 (ledger term, 30% weight) -0.00 (form penalty); score order put him at #27.

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 him (frozen performance-adjusted Elo; bouts before 2020 were in its tuning sample). Linked opponents have a profile.

Board position since Oct 2023

Position on the registered v1.0 board at each weekly snapshot (C = title holder or reserved, drawn at the top; lower is better). Absent from 95 of 132 snapshots (gaps in the line).

Predictive rating by bout

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.

Trajectory

No trajectory index: it needs three decided UFC bouts and a bout within the last three years (config/decline.yaml).

Context flags

Descriptive only. Each line is a population fact about fighters like him, not a forecast for him; the register entries hold the measurements.
