RECENT FORM (last 5 shown; all fetched matches used)
A — Kovackova (junior; all matches Girls/ITF level):
07-08 L Eigelsbach (1630, Avg) 6-4 6-7 4-6 GRIND — Girls Wimbledon R16
07-06 W Zhang (1573, Avg) 4-6 6-3 6-1 GRIND
07-05 W Chang (1500, Avg) 3-6 6-4 6-3 GRIND
06-11 L Havlickova (1512, Avg) 6-1 6-7 6-4 GRIND
06-09 W Monnot (1403, Weak) 6-3 4-6 6-2 GRIND
→ 8-4 in window, but 0 DOM wins; every win a 3-set grind vs Avg/Weak junior/ITF
opposition. No WTA main-draw sample. Clay-comfortable (RG Girls SF), Czech at home.
B — Tararudee:
07-19 W Vandewinkel (1773, Strong) 3 sets — Istanbul 2 quali Final
07-18 W Valdmannova (1695, Strong) 6-2 6-0 DOM
07-17 W Zvonareva (1500, Avg) 6-3 6-2 DOM
07-15 W Knutson (1500, Avg) 3 sets GRIND
07-13 W Okamura (1500, Avg) 6-2 6-1 DOM
→ 5-0 streak incl. DOM wins vs Strong; established WTA level (Eastbourne SF,
Nottingham SF, Wimbledon MD in June). Thin clay sample (1 loss in window).
FATIGUE
A: 0 matches/7d, 3/14d, 279 min, last match 07-08 → 12 days rest, fresh.
B: 4 matches/7d, 12 sets, 276 min, back-to-back, won YESTERDAY (07-19) in Istanbul,
then hard→clay switch + Istanbul→Prague travel. Clear freshness edge A.
NARRATIVE
B LETDOWN flag: won "Final" 1d ago — but it is a QUALIFICATION final, weaker than a
title letdown; she blitzed through it (6-2 6-0 in SF) despite the load.
Schedule anomaly: Istanbul quali final 07-19 → Prague main draw 07-20 — data doubt.
Venue: no Prague history either side. A is Czech (home soil) — mild.
ALT MARKETS (Betfair): AH A+4.5 @2.20 / B-4.5 @1.77 | Total 20.0 O2.04/U1.91
Model AH: null. Model total: 19.5 O 59.2% — but the sim is anchored on the inflated
65% ELO win-prob for A, so its tight-match projection is not trustworthy.
VERDICT — PASS
ELO 65% A is a junior-pool artifact: A's entire sample is junior/ITF ELOs and all her
wins are grinds vs Avg/Weak. The only model that disagrees with the market is the one
we can't trust; ML (18% A) sides WITH the exchange (25%). The fatigue/letdown case on
Tararudee is real (4-in-7, title match yesterday, travel, surface switch) but she is
posting DOM scorelines through it, so blowout risk stays live: A+4.5 cover ≈ 0.50-0.53
vs 0.467 effective break-even @2.20 — inside noise with no model AH support. Total edge
evaporates once the sim's win-prob is discounted. ML A @4.0 needs p(A) ≥ ~0.27 for the
5% bar; honest p(A) ≈ 0.25 given zero WTA-level evidence. No market clears the bar.
