MODELS
ELO A 67.6% | ML A 41.5% | blend A 55.0%
Book: A 2.90 / B 1.41 (soft/stale - B implied 71%). Betfair ML: A 2.52 (39.7%) / B 1.64 (61.0%).
Baseline sim: A 85.1% (!) - spw .581 / rpw .435 (elite return), B hold .79 but win 14.9%.
EDGE-ORIGIN DIAGNOSIS (farmed-stats contamination)
ELO-favourite yet ranked 116 vs a genuine top-25 = classic farmed-rating flag. Svrcina serve/
return inputs (rpw .435 = elite) built on weak clay/junior fields (finals vs ELO 1468-1716).
Darderi inputs (spw .557/rpw .382) DEFLATED by facing De Minaur 1869, Ruud 1999, Zverev 2040,
Paul 1952, Rublev 1935. So ELO(67.6%) and sim(85%) both over-rate A for the same reason; ML
(41.5%) alone tracks the market.
Correction (justified by field-strength asymmetry, each within +/-0.05): rpw_a .435->.385,
rpw_b .382->.432. Corrected sim => A 38.25% / B 61.75% - CONVERGES with ML (41.5%) and Betfair
(A 39.7% / B 61.0%). The Svrcina-favouring signal was an artifact; no model truly disagrees.
RECENT FORM
Svrcina: 07-29 Los Cabos HARD d. Walton (1756) 3-set grind (2 TBs) - match-sharp on surface,
played-in. Prior window clay-heavy, mixed (L Dimitrov, L Dedura, L Tien). Won 3-setter 07-29
-> mild day-after hangover risk. SHARPENING on hard but off a farmed base.
Darderi: legit top-30 - Bastad final (l. Rublev), Rome QF beating Zverev/Paul/Jodar. Off a deep
CLAY run (Estoril SF 07-25). First match at Los Cabos, clay->HARD transition + travel = rust/
transition risk. Heavy 14d load (7 matches, 962 min) but 4 days rest - not an extreme spot.
FATIGUE / NARRATIVE
Neither in an extreme spot (Darderi last played 07-25, 4 days off; cumulative minutes = context
only per calibration). Svrcina won a 3-setter 07-29 (mild hangover, age 23 baseline). Both
transitioning clay->hard; Svrcina already has one hard win here, Darderi does not - a genuine
qualitative point FOR Svrcina, but it cannot create a numeric edge (G1) and is offset by his
farmed base + hangover.
MARKETS (all off the corrected, market-convergent distribution)
ML: A ~38-41% vs 2.52 (39.7%) - no edge; B ~62% vs 1.64 (61%) - ~+1%, below bar.
Handicap 2.5: A +2.5 covers 49.5% vs 2.0 (adj impl 51.3%) = negative; B -2.5 covers 50.5% vs
1.92 (adj impl 53.4%) = negative. Coin flip at the line, both sides priced through.
Totals: corrected exp games 22.0, sits exactly on market line 22.0 -> under ~0.51 vs 1.93
(adj impl 53.1%) negative; over ~0.49 vs 2.02 (adj impl 50.8%) negative. No edge.
GATES
G1 edge-origin: FAIL - only model-vs-market gap was farmed ELO/sim favouring Svrcina; corrected
sim converges with ML+market at B ~62%, so no numeric origin edge on any market.
G2 consensus: n/a (stake tier only) - no bet reaches staking.
G3 fatal-risk: n/a - no margin bet constructed.
VERDICT: Efficient market. The Svrcina value mirage is a farmed-rating/farmed-stats artifact;
once inputs are field-corrected, corrected sim, ML and Betfair all agree Darderi is the ~61-62%
favourite, and every priced market (ML both sides, handicap 2.5, total 22.0) is at or through
fair. No edge to stake. PASS.
