Hi La Mer, the 4 horses are actually the top 4 horses in ranked order of my selection system that I am experimenting with. The top ranked runs a place 48.5 % of the time and so on. The point regARDING THE CLASS THEY RUN IN DOSENT REALLY HAVE AN EFFECT AS the results come from horses running in similar classes. Thanks for the replies anyway gents, as I will continue my trek towards the Holy Grail.
