If you can consider this race, at this track, in these conditions, with this number of runners and then get the factors that produce winners. The track, the distance, the class, the number of runners, and the going are all common to this race and apply to all the runners. The barrier, the speed of the horse, the fitness, the jockey etc are not. The factors that produce winners in this particular race type may only be 2-4 in number. A 7 horse sprint race will require different winning factors than a 15 horse distance race.

Hence you may have a better result researching these winning factors for each race type, rather than trying to find the winning factors in all races.
