+920 is a longshot. The bookmaker prices the outcome at 9.80%, and the payout of 920.00 per 100 staked is the compensation for how rarely it lands. Longshots carry more margin than any other part of the market, which is why devigging methods disagree most at prices like this one.
The vig at +920
If both sides of a two-way market were priced at +920, the implied probabilities would add up to -80.39% above 100%. That excess is the overround, or vig; as a share of stakes it is a -410.00% margin for the bookmaker. Removing it leaves fair odds of 2.00 decimal ( +100) on each side. Use the devig calculator to do the same for any market.
