Tab V Betfair Comparrison
 

Does any one have some stats on odds on fav prices compared to betfair Back/Lay prices.

For example if the Tab prices say $1.70 what price could you expect betfair back/Lay prices to be.

For <= $2.00 on Best Tote. Returns 6% less then best tote after commissions applied of 6.5%.

UB, are these stats that you're providing, based on what your bot records before the official start time to give it time to place a bet OR the official Betfair Closing Back price that could, in later races, be one or two minutes after the official start time? Big difference in values at times?

Its at 10 secs to the jump when they are recorded. Yes you are right there could be some differences but I wouldn't expect them to be huge.

Which is why the back tote / lay betfair scenario doesn't work, after commission and levy, it's a zero sum game.
