Grade any bet against the whole market.

Every sportsbook price wraps the true probability in vig. The engine pulls the live lines for your player and stat across 25+ books, strips the vig with the same de-vig methods the scanner runs, and averages the estimates into a consensus fair probability. Your odds are then measured against that fair line: the further your price sits on the right side of it, the higher the grade.

The factors list tells you what moved the number — how many books back the consensus, whether your book runs soft or sharp, and where a better price is posted right now.

What does the 0-100 grade mean?

It's the same calibrated Whet Score the scanner puts on every prop: your price measured against the de-vigged consensus of 25+ sportsbooks. Higher means the market says your price is better than fair. It is a read on the price, not a prediction of the outcome.

Why does it say 'limited market data' sometimes?

The grade is only as good as the market behind it. If few books are posting your exact player, stat, and line right now, the engine says so and grades from a single-book estimate instead of pretending it has a consensus.

Can I grade bets from any sportsbook?

You can enter any book. Grades are sharpest for the US books the scanner tracks; sharp reference books like Pinnacle set the fair line, so a bet placed there rarely grades as +EV — that's the math working, not a bug.

Is a 90 grade a sure thing?

No. A high grade means the price beats the market's fair estimate — a 55% favorite still loses 45% of the time. Nothing here is betting advice.
