Xanadu,

Appreciate your advice. My use of pre-post prices is not from a value perspective, but a rating perspective.

I have found this filter to be a very good field 'culling' tool. In my analysis of the past year and half, I have found over 70% of winners come from the Top 6 pre-post rated horses.

PS: Thanks for the jockey tip. It came to good effect today!
