Some time ago I layed horses if their jockey had a poor career strike rate which also covered the past 12 months. I can't remember my maximum price but the method failed.

I seem to think the worst results came from minor race race meetings. I can only assume the jockeys may have had several races against better jockeys resulting in a distorted low strike rate. However I did not combine the jockey and trainer strike rates, nor any other filters.
