The reason why Adrians site says 34% Win SR is because that includes duel Favs.

Without the duel favs & it becomes 30%

UK Favs often pay more because they often have large fields especially the Irish races where the Fav could be as high as 11.00 & they sometimes still win.
This can throw the averages out somewhat.


Generally Betfair pays 20% more.
One has to allow for the 5% commission
Which makes its net price 15% more than the TAB.

Its funny how certain punters wine about the 5% Betfair com,
but say nothing about the TAB's 18.5% loading which includes their rounding down of of divs paid e.g. Calculated div 3.09 TAB rounds down to 3.00
That's a 4.5% take for nothing
One has to use fractional odds to work out the calculation.
