Marwan Rahiki

Featherweight · REAL v1.0 (registered) #31; v1.1 (shadow) #37

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 26-34: the 10th to 90th percentile of his position across weight vectors drawn near the 70/30 weights. Rating 1,563, deviation 215: measured from 3 UFC bouts; a one-bout newcomer sits near 290. Provisional: 3 UFC bouts; the rating rests on little evidence.

Why he is ranked here

Rating 1,563 is the division's 33rd highest of 94 board fighters; the ledger stands at -1.0 (less 1.0 for other losses outside the top 5; losses count for three years); 0 quality wins in 15 years, 0 over top-10 opponents; no form penalty (2-1 last five). Score +0.09 = +0.09 (rating term, 70% weight) +0.00 (ledger term, 30% weight) -0.00 (form penalty); score order put him at #31.

Rules, weights and worked examples: methodology.

All 3 UFC bouts

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.

Career statistics

Through 2026-10-31, UFC bouts only. Percentile = share of the 94 board fighters at Featherweight at or below this value; high is a position in the division, not a verdict.

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 100 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

Recent performances are in line with the rating (+12 points).

Performance relative to the rating, by age

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).

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.

• Age unknown (no date of birth on UFCStats), so no age band is shown.
• Provisional: 3 UFC bouts; the rating rests on little evidence (deviation 215).
• Not raised: no KO/TKO loss in the last 90 days; last bout within 12 months.
