Featherweight · REAL v1.0 (registered) #57; v1.1 (shadow) #55

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 56-61: the 10th to 90th percentile of his position across weight vectors drawn near the 70/30 weights. Rating 1,472, deviation 237: measured from 2 UFC bouts; a one-bout newcomer sits near 290. Provisional: 2 UFC bouts; the rating rests on little evidence.

Age 33 (born 1993-05-19) · Height 5 ft 11 in (180 cm) · Reach 73 in (185 cm) · Stance Switch · 463 days since last bout (2025-07-26) · Last five 1-1 · Streak W1

Why he is ranked here

Rating 1,472 is the division's 74th highest of 94 board fighters after an inactivity penalty of 28 points for 463 days without a bout; the ledger stands at -1.0 (less 1.0 for blowout losses; losses count for three years); 0 quality wins in 15 years, 0 over top-10 opponents; no form penalty (1-1 last five). Score -0.17 = -0.17 (rating term, 70% weight) +0.00 (ledger term, 30% weight) -0.00 (form penalty); score order put him at #57.

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.

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.
