Mandel Nallo

Lightweight · REAL v1.0 (registered) #52; v1.1 (shadow) #46

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 50-54: the 10th to 90th percentile of his position across weight vectors drawn near the 70/30 weights. Rating 1,515, deviation 214: measured from 2 UFC bouts; a one-bout newcomer sits near 290. Provisional: 2 UFC bouts; the rating rests on little evidence.

Age 37 (born 1989-07-26) · Height 6 ft 0 in (183 cm) · Reach 75 in (190 cm) · Stance Orthodox · 15 days since last bout (2026-10-17) · Last five 1-1 · Streak W1

Why he is ranked here

Rating 1,515 is the division's 63rd highest of 96 board fighters; 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 -0.08 = -0.08 (rating term, 70% weight) +0.00 (ledger term, 30% weight) -0.00 (form penalty); score order put him at #51; the head-to-head rule (the winner of the most recent meeting within three years moves directly above the loser when ranked at most three places behind, six within a year) placed him #52.

Rules, weights and worked examples: methodology.

All 2 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 96 board fighters at Lightweight 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 105 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.

• Age band: 36 and over (age 37). On the board's own history (3,748 bouts between two board fighters, 2014 to 2026) the higher-scored fighter won 64% of bouts when under 30, 59% at 30 to 32, 57% at 33 to 35 and 42 to 46% at 36 and over (EXP-2026-10-20-09). A population rate, not a forecast for him.
• Provisional: 2 UFC bouts; the rating rests on little evidence (deviation 214).
• Not raised: no KO/TKO loss in the last 90 days; last bout within 12 months.
