Naef (1627, Avg) 6-1 6-4 - 04-26 Huzhou (clay): L vs M. Guo (1244, Weak) 3-6 3-6 31 days without a match at age 35 - rust; her model probability rests on a stale rating. FATIGUE - A: 5 matches/14d, 15 sets, 394 court-min, 2x back-to-back, played yesterday (lost Saskatoon QF). Age 28 - baseline, no age softening: disadvantaged on raw load. - B: 0 matches/14d, fully rested - but rested via a month of inactivity at 35, which is rust, not freshness. Net: mixed; fatigue cannot create an edge regardless (G1). NARRATIVE - Let-down: none (no recent Final either side). Venue: no Vancouver history in window. Surface transition: none (A hard-to-hard; B inactive). GATES G1 edge-origin: [PASS] - model 27.7% B vs Betfair-implied ~14.6% (7.2, comm-adj 6.89) is a pre-adjustment numerical gap G2 consensus: [PASS] - ELO and ML both price B above market; models are not against the value side G3 fatal-risk: [FAIL] - the edge rests on stale/unreliable ITF ELOs: Kuwata is 0-3 in 90d with blowout losses incl. to a 1244-ELO player, 31d inactive at 35; Kuramochi rating farmed vs default-1500 fields. If the ratings are stale - and every live result says they are - the 27.7% for B evaporates and the thesis is dead. VERDICT: PASS. The model-market gap on Kuwata is a data artifact, not value: she has not won a match in the fetched window and her losses are blowouts to weaker opposition. Both ELOs in this ITF-level matchup are low-quality (default-1500 opponents, month-long inactivity), and this is the low-liquidity segment the backtest loses on. Kuramochi fatigue (394 min, played yesterday) is real but cannot buy back a bet on a player with zero live evidence. No alt markets priced.
