Hi benny ,
What I know , is this will almost guarantee consistant short prices at ordinary S/Rs , not good, it will not fly longterm .

I feel one of the best ways for a punter to get in front, is to get hold of a source that has a 40-45 SR with its top 2 , then work out a method of splitting them.
e.g.Bet the one of the 2 that has either 1st of 2nd result in either of its last 2 starts.
If a draw , no bet.
