Did 12 months research on Perth dogs. Box the first three prepost in west paper and the last priced dog for quad.

I found that these came in at the same rate as first four prepost and than the other combinations 1,2,3&5or 6or 7

Also found this to give an even return which was considerably better than the first four. The odd time that the last stood up made it difficult not to leave out of boxing it in for the win.

Something may be done on a data base with this as a start. leave out some races or add some filters. I don't know I was doing it longhand.
