I have collected the neurals for a while now and there are very few combinations that show a profit over 7 months data.

BUT combine a good combination that seems to make sense (which only loses 5% over 7 months betting every race) with a few filters .. for example ran in last 15 days, inside barrier, Field size restriction, starts at a certain price, placed 3 starts, etc, etc, etc, and it suddenly turns into a very good system (or several good systems). These filters were just an example ...

Even using the default settings will give you a good enough profit when used in conjunction with other free ratings and an extra filter.

Good Luck.
