Tahir Abdullayev

Welterweight · REAL v1.0 (registered) #30; v1.1 (shadow) #28

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 30-31: the 10th to 90th percentile of his position across weight vectors drawn near the 70/30 weights. Rating 1,545, deviation 291: measured from 1 UFC bout; a one-bout newcomer sits near 290. Provisional: 1 UFC bout; the rating rests on little evidence.

Age 29 (born 1997-02-02) · Height 5 ft 8 in (173 cm) · Reach 73 in (185 cm) · Stance Orthodox · 127 days since last bout (2026-06-27) · Last five 1-0 · Streak W1

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.

Predictive rating by bout

1,5001,550Jun 2026Oct 20262026-06-27: 1,523 (W vs Jefferson Nascimento)1,523

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.
