Thanks Chuck,

This is the one problem I have with regards to prepost etc.
I have TAB closing prices in my database but not prepost prices. The whole crux of a couple of systems on this forum, is utilizing the prepost market, therefore any results I give on those systems would not be a true indication of the performance.

Sportznut's barrier system is worth giving a shot because outside barrier horses in general are a little more over their odds than they should be, except in small fields.

The problem is that there are not many selections as Sportznut concluded himself.
