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 from the books pricing that exact market, strips the vig the same way the scanner does, 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 the books actually pricing that player, stat and line. We need at least two of them quoting both sides before there is anything to measure, and three backing the fair line before a grade is issued. 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 sometimes refuse to grade my bet?

The grade is only as good as the market behind it. A Whet Score is your price measured against what every other book is charging, so if fewer than two books are posting your exact player, stat, and line right now, there is nothing to measure against — and we say that instead of grading your own price back at you.

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.
