M. Uchijima (A) vs M. Kuramochi (B) — Vancouver, hard, 1/16-finals
MODELS vs MARKET
ELO A 74.0% | ML A 70.8% | Sim A 67.3%
Book A 75.4% (1.24 / 3.8) | Betfair A 85.5% (1.17) / B ~23.3% (4.3)
value_pick B (edge 8.1% vs BOOK). Executable B price 4.3 -> comm-adj eff 4.14,
1/eff = 24.2%; sim B = 32.7% -> nominal ~8.5% edge on B.
Every single estimate has A winning 67-85%. The SHARPEST price (exchange)
is MORE on A (85.5%) than the models are. The "B value" is purely the sim
sitting below the book, i.e. an edge against the sharpest price.
RECENT FORM / SHAPE
Uchijima (A) — FADING. Ranked 107 but dropped to W15 Brisbane and LOST the QF
6-1 6-3 to a 1500 (07-24); string of losses on clay (Bondar, Avanesyan, 3-set
loss to a 1490 Burillo). Last hard court: LOST 6-4 6-1 to a 1298 (W35 Wichita,
May). Coming off clay/W15 onto hard = TRANSITION (rust + wider margins).
Kuramochi (B) — SHARPENING but on WEAK fields. Won the Vancouver title TODAY
(07-28, 7-5 6-3 vs 1167); hard-court run for weeks. BUT her wins are all vs
sub-1350 opponents (Alexander 1167/1111, Kuwata 1247, W15 Sapporo defaults).
Classic level-dropper: sharpness inflated by weak fields (Step 1b).
FATIGUE (Step 2)
Kuramochi is the EXHAUSTED side: matches_7d=5, matches_14d=7, 560 court-min,
just completed a title FINAL today (last_match_date 07-28). Uchijima
comparatively fresh (last match 07-24, ~4 days). No 3-set hangover haircut
(both her recent wins were 2-setters), but the cumulative load points the
fatigue edge TOWARD A, not toward the dog I'd be backing.
NARRATIVE
Kuramochi won a Final today -> LETDOWN risk on B (the side value_pick backs).
Surface transition on A (clay/W15 -> hard) widens margins but does not create B value.
ELO/rank agreement: A ELO (74%) roughly consistent with rank 107 vs 351 — ELO credible.
GATES
G1 edge-origin: PASS — numerical sim-vs-price gap on B (~8.5%) exists pre-narrative.
G2 consensus: FAIL — market AND ML (and ELO, book) all sit on A; the exchange is
even heavier on A (85.5%). No hard independent evidence for B — her live results
are vs sub-1350 players, no on-surface H2H. Consensus is unanimous for A.
G3 fatal-risk: FAIL — backing B rests on "sharp dog fades the fading favourite,"
but the negating risks are all present and true: (a) real class gap the whole
market prices bigger than the sim, (b) B's sharpness is weak-field-inflated,
(c) B is the EXHAUSTED side (title final today, 5 matches/7d) — a tired dog gets
run over, not kept close. Units cannot buy back a negating risk.
VERDICT: PASS. The only "edge" is the sim printing below a book/exchange that has
already fully digested Uchijima's ugly form and STILL makes her a 67-85% favourite
across every estimate. Fading the fading-favourite here means fighting the sharpest
price with a weak-field-inflated, title-fatigued dog in a thin W-ITF market. No A
bet either (exchange 1.17 is far below every model — negative value). Textbook PASS.
