Does +EV betting actually work?

Ask “does +EV betting work” and most sites answer with a win-rate percentage, because a big win rate looks convincing. It isn't the right number. A record built on favorites can win 58% of the time and barely break even, while a record at plus-money odds can win under half its bets and still profit. The measure that prices in the odds is realized ROI, profit per dollar staked across the picks we put on the board, which is the number we lead with above.

The hurdle every bettor has to clear first is the vig: on a standard two-way market the book bakes in roughly a 4–5% margin. That's why sustained ROI in the low single digits is a genuinely strong result over a large sample, and why anyone advertising 20%+ long-run ROI is almost always showing you a tiny or cherry-picked slice. Our ROI is measured at the price we surfaced, graded against the real outcome. The losses stay in the average next to the wins.

Every pick the scanner confirms is written to the ledger the moment it's made (player, line, side, odds, book), before the result exists, so nothing can be edited after the result is known. The next morning we grade each pick against the real result, at the surfaced price.

Does +EV betting actually work?

Positive-EV betting works when the price you take is genuinely better than the market's fair price and you keep taking it across a large sample. The edge shows up as realized ROI over hundreds of graded bets, not on any single bet. This page shows Whet's realized ROI on the picks on the board, under a rule published before the results were known. Every pick Whet grades, shown or not, is public on whet.gg/proof. It is a track record, not a promise: any given bet, or any short stretch, can lose.

What is a good ROI in sports betting?

Sustained ROI in the low single digits per bet is strong. Sharp bettors live in roughly the 1–5% range over large samples, because the sportsbook's vig (typically 4–5% on a standard two-way market) is the hurdle you have to clear first. Anyone advertising 20%+ long-run ROI is almost always showing a tiny or cherry-picked sample. The number on this page is realized ROI at the price we surfaced, across every pick we put on the board. Every pick Whet grades, shown or not, is public on /proof.

How is this track record measured?

Every pick the scanner confirms is logged the moment it's made and graded against the real game result, wins and losses, in the public ledger at whet.gg/proof. ROI is realized profit at the price we surfaced, measured on the same flat bet every time; the ledger publishes it in dollars at $10 flat bets.

Does past ROI predict future results?

No. This is a record of what has already been graded, not a forecast. Lines move, edges close, and variance is real. A positive track record lowers the odds you're fooling yourself, but it guarantees nothing about the next bet. Bet only what you can afford to lose.
