Bet value is the multiplication of odds and prediction probability. Eg. If for the Murray-Simon match, odds that Murray wins is 1.4, the bet value is 1.05 (1.4 * 0.75 = 1.05). The higher the bet value the better. On the long term, only matches having a bet value of 1.0 or above are profitable. If you start playing with the Backtest
