Every feature, in depth.

The price you see on a book is wrapped in the book's margin (“the vig”). Strip the vig, and the price reflects the market's true estimate of probability.

Whet ships five de-vig methods. The scanner runs Shin on every two-way market, because it fits prop markets where one side knows more than the other. The free no-vig calculator runs four of them side by side so you can see how far apart they land.

A +EV number on its own is not a bet. Most of what any scanner turns up is a stale quote, a thin market, or one book disagreeing with everyone else. Whet drops those before the pick reaches your board. Every gate below runs on every pick, every cycle.

• Two-way consensus — the fair line is built only from books quoting both sides of the market. A market nobody prices on both sides is skipped.
• Three independent books, minimum — the best price has to be one at least three independent books agree on, within two points of implied probability. One book quoting an outlier is not an edge, it's an error. Fitted on 21,782 graded MLB picks.
• Stale-price rejection — a quote more than 15 cents off the consensus is dropped rather than scored.
• Minimum edge — 3% EV on player props, 2% on mainlines. Below that the vig eats the edge.
• Injury gate — props for players ruled out are removed before the board renders.
• The over penalty — MLB prop overs lose 35 score points, because our own graded record says overs underperform. We penalise our own picks when the data tells us to.

Kelly tells you what fraction of bankroll to risk given an edge. Full Kelly is too aggressive for variance; fractional Kelly (quarter, half) is the standard. Whet ships quarter-Kelly by default, capped at 3% per bet — math you can verify, not a black box.

For same-game parlays, the parlay scorer prices linkedlegs honestly: a hit and total bases for the same batter are correlated, because the same swing pays both, so the fair odds account for it instead of pretending the legs are independent.

Every prop gets a Whet Score: a single 0-100 ranking that fuses edge, confidence, market width, and how strongly the cross-book consensus confirms it. 90+ is the top band; 75-89 is great; 60-74 is good; 40-59 is okay; under 40 is a skip.

The score isn't a black box — every input is visible on the prop card. If you disagree with the math, you can see which input is driving the score. If you trust the math, the score tells you which one to take and which one to skip when you've got more +EV bets than bankroll for.

For the bets you log, we record the last consensus price we archived for that market. If you bet Judge over 1.5 total bases at -108 and the market's last archived price is -120, you beat the market by 12 cents — the bet was sharp, regardless of whether it won. Over a sample, CLV stabilizes faster than win rate does; measured honestly, it's the strongest single signal that an edge is real over a short window.

Whet's CLV dashboard shows your closing-line value by sport, by stat type, by book. If your CLV is positive but your ROI is negative, you're just running bad. If your CLV is negative, the system isn't finding what it claims to find — and you should pause.

One honest note on the anchor: per-bet CLV is measured against the last consensus price we archived — not a true closing line — for now. A sharp-anchored measure (Pinnacle's two-sided closing quote) is accruing and replaces it once its pre-registered sample floor is met — the same bar /forward-test sets for every number we publish.

The replay simulator re-scores picks we have already graded. You change the EV floor and the Kelly fraction and see what the record would have been. It reuses the fair price stored at scan time, so it tests the cut line and the bet size, not the whole pipeline.

You can simulate Kelly fractions (full versus quarter versus flat). You can raise the EV floor and see which picks would never have been issued. Sharp tier only.

When two books disagree on a market by more than the combined vig, you can lock in a guaranteed return by betting both sides — on paper. That's arbitrage. The catch: arb windows close in seconds, and arb-only players get limited fast.

Whet's arb scanner runs when you open the Arbitrage tab, over the newest completed batch of odds from the last ten minutes, and it re-checks every 30 seconds while the tab is open. It reads player props only, so game lines are not covered. For each window it finds, it splits a fixed total stake across the two books. It does not know your accounts or your limits. Sharp tier only.
