Highlights

• • Market implies Jana ~88.5% but research provides no justification for that dominance.
• • At our 50% estimate, the away price 5.5 yields EV = +1.75 (very large positive ROI).

Pros

• + Large margin between our conservative probability estimate and market odds creates clear positive EV.
• + Research shows no injury or form difference to justify the book's lopsided pricing.

Cons

• - Our estimate is driven by limited data in the supplied research; real-world factors (ranking, travel, late withdrawals) not in the research could justify the market price.
• - Extremely lopsided market implies bookmakers may have additional information not present in the provided sources; this increases model risk.

Details

We find a large discrepancy between the market price and the information available in the research. The book is pricing Jana Kolodynska at 1.13 (implied win probability ~88.5%) and Lexue Xiao at 5.5 (implied ~18.2%). The provided player profiles show nearly identical records (both 10-21 across 31 matches) and similar recent results with no injury notes or surface-specific advantage in the research. With no clear edge evident for the heavy favorite, we estimate the players as essentially even on the provided evidence (true win probability for Lexue Xiao ~50%). Comparing our estimate to the market: required fair decimal odds for a 50% chance are 2.00, while the market offers 5.50 for the away. That creates substantial positive expected value on the away side (EV = 0.5 * 5.5 - 1 = +1.75). Because our estimate is driven entirely by the supplied research (which shows parity between the two players), the away price represents clear value versus the book's implied probability.

Key factors

• • Both players show nearly identical records and recent-match information in the provided research (no clear edge).
• • Market is extremely skewed: home implied ~88.5% vs away ~18.2%, which conflicts with the supplied parity evidence.
• • No injury, surface advantage, or H2H information in the research to justify the heavy favorite price.
