Thanks for the quick replies. I'm just trying a few things at the moment and I don't have the stats to check it out, so I appreciate the help.

I was wondering if you could do the same thing, but instead of winning last start, they were a beaten favourite who ran a place, and also won second last start. So, the rules are:

(a) Beaten favourite last start who ran a place
(b) Won second last start
(c) Won at todays track and distance (c in recent form)

Again, thanks for the help
