TennisEdge's AI model finds no betting value in A. Alexander vs M. Okalova (Vancouver on 2026-07-25) — the market is efficient, with M. Okalova favoured at 1.42.
MODELS vs MARKET
ELO A 19.8% | ML A 28.6% | Blended A 33.5% -> B: ELO 80.2% / ML 71.4% / Blended 66.5%
Book: A 2.62 / B 1.42 (B implied 70.4%) | Betfair (executable): A 2.26 / B 1.70 (B implied 58.8%; eff 1.665 -> 60.1%)
Numeric edge B at exchange: 66.5% - 60.1% = ~6.4% (pre-narrative). Book vs exchange gap on B (1.42 vs 1.70) is huge -> thin/unreliable market.
DATA RED FLAG: Player A record shows age 56, ranking 5 - clearly corrupted; ELO/ranking sanity check unusable, model inputs suspect.

FATIGUE
A: 3 matches/14d, 9 sets, 189 court-min, back-to-back, last 07-23. Listed age 56 (corrupt) -> treat age-neutral on the raw rule.
B: 1 match/14d, 68 min, last 07-12 - rested but rusty + surface transition.
Court-time diff 121 min > 60 -> A disadvantaged on the raw rule. Not used to build any edge.
NARRATIVE
Let-down: none (no recent finals either side). Venue: no Vancouver history in window for either. Titles: none.
Surface transition: B (clay -> hard) - depresses level, widens margin variance.
GATES
G1 edge-origin: PASS - blended B 66.5% vs exchange 60.1% = 6.4% pre-narrative edge exists numerically.
G2 consensus: PASS - market and ML both have B as winner; no consensus against the pick.
G3 fatal-risk: FAIL - thesis of B winning 66%+ is negated by B's own live results: 2-6 last 8 with blowout losses to 1410-1578 opposition, clay->hard transition, 13-day layoff. Model ELO for B contradicted by live form; plus corrupted player-A record (age 56 / rank 5) makes model inputs untrustworthy.
VERDICT: PASS
The only edge is model-vs-exchange on Okalova, but the model leans on an ELO gap her recent results flatly contradict, the player-A data record is corrupted, and the book/exchange price gap flags a thin market. Qualitative read undermines rather than validates the numeric edge. No bet.
