Just a word of warning in case betfair come out with a similar system in future. This is how they calculate the rebate. Assuming 50% pc and ignoring the pennies of comm generated.
A method of averaging premium charges to various bets placed during one week is ultimately a nonsense as determined by the wildly different and insane conclusions it would draw time after time.
Hope this helps
Kind Regards
