Stix,

I generally don't bet on heavy tracks, but I often do on a slow track on a Sat. when all major meetings are wet.

Due to lots of scratchings on heavy tracks [poor prices] and often much smaller fields, it's obviously easier for a system tailored around back-fitted winners and back-fitted SP prices, to have performed OK on paper. It's also easier to find a winner or place-getter in a 4 or 5 horse race too and there is plenty of those small fields around [Syd. comes to mind regardless of the conditions]!

Lets see a heavy track system work in real time when SP prices can often fluctuate to any old price after the jump:-)
