Frequently asked
What's the model's edge on John Yannis @ Marcus McGhee?
The Lakeshore Edge model rates John Yannis at 21% to win or cover, versus FanDuel's implied 22% — a marginal edge of -1.1pt. That gap is what the model flags as a potential bet. The model has averaged +4.2pt CLV across 296 graded singles, meaning prices it picks tend to drift in the bettor's favor before close.
How likely is John Yannis to win according to the model?
21% by the Lakeshore Edge model. Pinnacle, the industry's sharpest book at ~2% vig, has them at 19.8%; Polymarket's real-money traders price the same outcome at 20.5%. The model blends Elo, recent form, sport-specific factors (pitching, injuries, weather), and live line movement to land on that number.
Why does the model disagree with the sportsbook?
FanDuel's price implies 22% on John Yannis, but the model has it at 21% — a -1.1pt gap. The model's reasoning is fully visible in the waterfall above; each adjustment stage is logged so the call can be audited after the game.
What's closing-line value (CLV) and why does it matter?
Closing-line value is how much your entry price beats the market's closing price on the same bet. If you pick a side at FanDuel -130 and the line closes at -150, the line moved 4pp toward your side after you locked in — that's positive CLV. CLV is the leading indicator of long-run profit because it's the metric that survives variance: a sustained positive CLV means you're consistently getting a better price than the consensus market settles on. Lakeshore Edge averages +4.2pt CLV on 296 graded singles, beating the close on 90% of them.
