wesmip1,

Can I suggest that the filters you are providing are not sufficient.

Maybe think about why they are all losing money and what factors need to improve the performance of the horses as opposed to the performance of the ratings.

Bear in mind that the Unitab ratings are ratings based on peak recent performance, therefore they will always be unders unless you find an angle different to form , as they are form based already.

What about class rise/drop, gear changes, country horses that come to town and are 100 rated, days since last run - fitness (not just first up or not), weight, not just placings but margins etc etc.

The edge is there, you haven't wasted your time, you might need to look elsewhere within the data.

Think about it this way, lets say that a 100 rated horse is the class horse of the race with the best form, of course it will always be unders, what else should improve the strike rate yet improve the average dividend?
