Or how could backing home, away, and draw all lose quite so much, when you would expect to be only slightly down if you backed all the options? Is it that the bookmaker's margin is between 1-2%?<br />How much is the bookmaker's margin on football matches, and does the data imply that the odds are broadly right (less the bookies spread)?<br /><br />This may be ignorance on my part as most of my activity is on betfair, where markets add up to 100.2%ish and Betfair takes its (healthy!) cut at the end.Eggmundhttps://www.blogger.com/profile/16088398057688040868noreply@blogger.com
