Intuitively this is not logical to me. What if the horse ran 4th. when it was way out of its class? What if it had shocking luck in running? What if the jockey rode it badly? What about 34 or 43? What about 24 or 45?
Sorry folks, but something so ridiculously simple as laying any horse that ran 33 or 44 in its past 2 starts in its current campaign is not the quick, easy, fix for someone who knows absolutely nothing about racing to consistently win money on horse racing.
