MODELS vs MARKET
Book: 3.75 / 1.25 (implied A 25.0%) — context only
Betfair (executable): 4.80 / 1.22 -> commission-adj eff 4.61 / 1.209 (implied A 21.7%, B 82.7%)
ELO prob A: 22.7% | ML prob A: 14.6% | Composite model A: 27.2%
Alignment: ELO ~= exchange (22.7 vs 21.7 — agree). ML (14.6%) sits BELOW market on A.
Only the composite blend shows an A edge (~5.5% vs eff exchange); its two components do not.
DATA QUALITY WARNING
Both histories end well before this event (Ansari last row 07-09, Sramkova 06-24) — the
entire Washington run for BOTH players is missing. Precomputed fatigue shows 0 matches
in 14d for two semi-finalists, which is impossible mid-event -> fatigue data is stale
and unusable; no live-event form is visible to validate anything.
RECENT FORM (visible history only, most recent 5)
Ansari: L Newport 1/16 vs Vidmanova (1604); L W100 Cary vs Evans (1428, TB set);
L W50 Palma QF vs Micic (1441); W Palma 1/8 vs Bonardi (1160); W Palma 1/16 vs Gay (1000).
Pattern: ITF-level grind, repeated losses to Weak/Avg opposition, 0 DOM wins vs Strong+.
Rank 290 reaching a WTA SF implies a hot qualifying/main-draw week — but it is invisible in the data.
Sramkova: L Wimbledon SF vs Kostovic (1704, 3 sets w/ TB — GRIND vs Elite);
W Wimbledon QF vs Hruncakova (1478, 7-6 7-6 GRIND); L W100 Zagreb vs Primorac (1464);
L Makarska vs Urhobo (1633); L FO 1/64 vs Grabher (1678).
Deep Wimbledon run a month ago; mixed before that. Clearly the class side here.
FATIGUE
Precomputed fatigue null-equivalent (0/0 for both) and contradicted by the live event —
treated as unknown. Age-neutral. No fatigue lean either way.
NARRATIVE
Let-down: Sramkova first Final scan = "WTA French Open - Final" Won 05-22 (64d ago) — None.
Ansari: W35 Monastir Final Lost 05-17 — too old, None. Venue: no Washington history for
either. Surface transition: both last seen on grass (Ansari Newport 07-09, Sramkova
Wimbledon 06-24) but both have played this week on hard at this event — transition
already absorbed, no signal.
ELO vs RANKING SANITY
Sramkova rank 118 and ELO-favorite — consistent. Ansari rank 290 with visible form full
of ITF losses — the composite model's 27% looks generous, not the market's error.
GATES
G1 edge-origin: FAIL — the only numeric edge (~5.5% on Ansari) comes from the composite
blend; ELO matches the exchange and ML is 7 pts BELOW market. No robust model-market gap.
G2 consensus: FAIL — market AND ML both against an Ansari pick; the one thing that
could validate her (this week's Washington run) is missing from the data entirely.
G3 fatal-risk: FAIL — stale histories + impossible fatigue rows mean the qualitative
layer cannot be trusted in either direction; any thesis would be built on absent data.
VERDICT: PASS
Backing Sramkova at 1.22 (eff 1.209, implied 82.7%) offers no edge — ELO says 77%,
negative edge. Backing Ansari at 4.80 rests on a composite-only signal contradicted by
ML and unverifiable with two-week-stale histories. No alt markets priced (handicap/
totals null). Skeptic wins this one: no bet.
