Hi All.
I am looking for stats on the relative win probability of Betfair SP Vs Actual Win ratio. Plenty of Stats available on the web using Bookmaker SP vs Win ratio available but I have come up nought on betfair SP stats. It is my observation that between 1.60 and 2.00 their is a narrow window where the win rate of a horse is higher than their price suggests although I have nothing concrete over the longer term to back that up. Anybody seem such or something to add?

All the BSP history data files are at http://promo.betfair.com/betfairsp/prices/ shouldn't be hard to run your own queries as the files include won/lost data as well as SP
