How it works
- Implied chance = 1 / decimal odds. The implied chances add up to more than one whole: the extra is the bookmaker margin (overround).
- Multiplicative: divide each implied chance by the total. Additive: take an equal share of the margin off each outcome.
- Expected value of a price = fair chance x decimal price - 1, per unit staked. A positive number is an estimate, not an outcome: any single bet can lose.
