Correct score probabilities

[rolfw64]

Does anybody has experience how accurate probabilities for correct score are? They deviate significantly form market odds.

Market odds must be less than fair odds computed by OW because of sportsbook's profit margin. The sum of OW's correct scores probabilities=(100/fair odds) is equal to 100%. The sum of market (100/odds) is around 110%.

That is obvious. But I noticed that odds for 0:0 often are double in OW compared to Betfair,

Betfair's and other market correct score odds are subject to the betting volume. Many bettors like to bet on the zero score 0:0, that's why the odds are less than they should be.
