Thats a bit why say what you will about greyhounds, but I feel like sometimes the little man (or woman) on the back of a horse can have too much impact on how a horse performs as well. Also being bigger animals that need everything to go right for them in terms of running position, pace, injuries, jockey, track conditions (the list goes on), I sometimes wonder why I don't put more effort into finding a way to being profitable on the hounds.
