Glossary
The six terms we use on the board, written the same way as the homepage.
- Edge
- The percentage difference between one book's implied probability and the vig-removed market consensus. A positive edge means that book is offering a better price than the rest of the market.
- Implied Probability
- The break-even win rate embedded in the odds. American odds of -110 imply ~52.4% — you need to win more than that to profit long-term.
- Vig
- The sportsbook's built-in margin. Both sides of a bet add up to more than 100%. We strip the vig to see the true market probability.
- Quality Score
- A sorting aid (0-10) combining line deviation from consensus, the number of books offering the prop, and implied probability. It's context, not a recommendation.
- Line Shopping
- Comparing the same bet across multiple sportsbooks to find the best price. A half-point or +10 in odds compounds over hundreds of bets.
- Win Probability
- The market-implied chance the bet wins, derived from stripping the vig from the consensus line. This is what the collective market thinks, not a proprietary model.
