ah ****************, thats why most of us are here trying to find the magic formula,

in short about 30% of favs win (seems to be the same % across all types and classes of races) stats go back to the 1700's or something so I'm told.

The answer to your question though is YES........... BUUT, b4 you get too excited this is what happens, overall 30% win and you will lose about 10% on turnover (enough to send you broke VERY quickly) in a nutshell, the higher the price bracket the more the loss on turnover, so look at odds on chances and the loss DECREASES (and the S/R increases)
