We have recently announced adding odd-even odds to the list of available odds in
Odds Wizard. However after thorough analysis, we have found that in vast majority of cases odd-even fair odds are always equal to 2.00 - 2.00. In few cases, there were 1.99 - 2.01 or 2.01 - 1.99. Bookmakers show their odd-even odds in the range 1.83..1.95. That means that line (market) odds are always less than fair odds, and from the viewpoint of the theorem (
