If you bet the top 4 of the free propun ratings and add 1 to the number of horses and accept that as your minimum acceptable price you would have to be in front yearly.

I would throw out the really short priced horses in the top 4 ratings and take the next 1 down ( i.e The 5th rated )

Short priced would be those odds on up to $3.00 ( especially in the last 4 races )

In general Fav backers should go home after race 4

Cheers.
