Golden Soul's maiden win 5 back was a significant late pace performance. However it was not repeated agiain in the next 4 races. But they also were not at Churchill Downs. In any case, even going back that far, it doesn't look so good.
I have found that EPR is a significant predictor in dirt routes ... and Ted had the brilliant suggestion that it probably has to do with the position of the horse on the 2nd call.
