4Legs Thanks
I have added the tote strike rate for the same price range. The conclusion that I draw is that it confirms that the Betfair prices are higher. I only went to $5.70 as that was as much as I had printed on my reference sheet. Still you take off commissions and you are behind the 8 ball.

The observation that I am making is that my tote analysis has 15% of races occur with the fav at over $4. Your results show on Betfair 27%. On the UK races this seems higher. 13 races out of 31 last night. Thats 42%. One can read into that higher average prices which should mean turning a commission loss into positive territory. Beton
