E. Jones vs C. Zhao - Vancouver (hard), 1/16-finals MODELS vs MARKET Book: Jones 1.08 (impl 83.6%) / Zhao 5.50 Betfair ML: Jones 1.03 / Zhao 1.43 - huge spread, illiquid; exchange prices Zhao FAR below book (5.50 vs 1.43), so the soft book dog price is a stale quote, not value ELO prob A: 83.5% | ML prob A: 87.0% | Combined: 83.5% value_edge: 0.06% on B - noise. Models and market fully aligned on Jones. ELO/ranking sanity: Jones 18yo, rank 147 vs Zhao 31yo, rank 426 - ranking gap agrees with ELO/market direction; credible. RECENT FORM (last 5 printed) Jones (A): L Akli (1500) 5-7 4-6 W100 Evansville; L Gasanova (1571) 3set Wimbledon SF; W Fruhvirtova (1570) DOM Wimbledon QF; L Galfi (1703) GRIND (two TBs) Ilkley; L Stojsavljevic (1354) Birmingham. Mixed patch, but deep runs and a DOM win vs Avg-Strong opposition; level clearly above Zhao's. Zhao (B): 2-5 in fetched window, lost 5 straight - L Stefanini (1576), L Mikulskyte (1301), L Naef (1642), L Zavatska (1605), L You (1610). Only wins vs Weak (1495/1381) in qualies. Poor live form, losing even to sub-1350 ELO. FATIGUE Jones: 1 match / 14d, 83 court-min, last 07-22 - fresh (age 18, recovers fast anyway). Zhao: 0 matches / 14d, last match 07-09 - 18 days off; rested but rusty, and TRANSITION grass -> hard (all recent matches on grass). Verdict: roughly equal; no fatigue angle either way. NARRATIVE Let-down: none for either. Venue: no Vancouver history in window. Titles: none recent (Zhao's only Final win was a qualifying-round label at Jiujiang 05-03, weak field). Transition: Zhao grass -> hard = extra rust risk on the dog side. GATES G1 edge-origin: FAIL - no numerical model-market gap; ELO 83.5% vs market 83.6% is dead-on, ML 87% only slightly above; edge on either side < 5% before any narrative input. G2 consensus: FAIL - market and both models agree on Jones; no independent hard evidence against consensus. G3 fatal-risk: N/A - no candidate bet survives G1/G2. PRICING Backing Jones ML: exchange 1.03, effective 1.0285 -> implied 97.2% vs model 83.5-87% - massively negative edge. Backing Zhao ML: model ~16.5% needs min odds 6.36; executable exchange price is 1.43 - automatic pass. alt_markets handicap/totals: null - no alt lines to price. VERDICT: PASS. Efficient market, full model-market consensus on Jones; dog in a five-match losing streak with a grass-to-hard transition; no priced market offers a positive executable edge.
