I’m looking into tennis betting models and wanted opinions from people who have worked with Pinnacle closing/opening prices.

For favorites, Pinnacle is usually treated as one of the sharpest reference markets. But I’m less sure about underdogs in tennis, especially lower-liquidity matches, smaller tours, qualifiers, Challenger/ITF, retirements risk, injury/news lag, and matchups where public bias may push favorite prices.

My question is:

Can Pinnacle underdog prices be trusted as a reliable “true probability” baseline for finding EV elsewhere, or do tennis underdogs need extra adjustment before using Pinnacle as the reference?

For example, if Pinnacle implies an underdog is 35% after removing vig, and another book offers odds implying 31%, is that usually enough to treat it as +EV, or are there known distortions in tennis underdog pricing that make this unsafe?

Interested in any experience with closing line value, underdog calibration, sport-specific bias, or differences between ATP/WTA/Challenger markets.

Codex is amazing and much better than Claude what i feel is lacking is the ChatgGPT desktop app it kinda files much worse than the corresponding Claude application both in user interface ability to split windows and local computer work.

Hey, I am currently working on an Ev betting website with a plan to expand my future product to include real-time markets, especially focused on soccer, but also want to include basketball and tennis.

I have already deployed an application to monitor and gather odd movements, place bets, and simulate profit with kelly sizing. As a sharp reference book, I use Pinacle

But find many of their lines to be stale and throw False ev signals, which, with more data, I can obvisoly filter myself later on by inspecting the data.

The question is, what do you guys use as a reference sharp betting platform for live markets, maybe Betfair exchange. Is there any other good reference sharp market with good live coverage?
