I'm surprised Betdaq are in line with the bookies. For an exchange with 100% book Betfair's method makes more sense as an even money favourite literally takes 50% of the book, whereas bookies have a much larger overround.ANGELS15 wrote: ↑Fri Mar 16, 2018 11:33 amI recall from a conversation with Betfair many years ago that when they apply a 'rule 4' they apply it to the whole return including the stake. In an example I'd backed a short price favourite Evs. there was 50p rule 4. with a conventional bookie or even Betdaq if you'd backed it at Evs for say £100 you'd be returned £150. However with Betfair as they apply it to the whole return you'd actually just receive back your £100 stake.
It's extremely unlikely that an even money favourite would have a 50% reduction on Betfair because it would mean the non-runner must also have been at even money!
