FAQs
What does "de-vigging" mean?
Removing the bookmaker's built-in margin (the "vig" or "juice") from a set of odds so the implied probabilities add up to exactly 100% — an estimate of the market's true view, without the bookmaker's cut.
What is bookmaker margin used for here?
It shows how much extra the bookmaker has priced into this specific market beyond the true probabilities, expressed as a percentage — a lower margin generally means better value odds for bettors.
