I\'ve done similar to this, typically inconclusive because half are above and the other half below any set standard. I\'ve had better success \"dividing\" the winners into 4 areas of their race. I.E. first flight of horses, second flight of horses, third flight of horses, and fourth flight. Separating where the winners were DURING the race to draw a correlation as to their ability to finish while near the front end, from well of the pace, etc. Seems dosage has become less relevant over the years, but the ability to finish in the first flight, or the trailing flight has shown some promise. War Emblem and the front running types fare differently than others not having a lot of speed. Its still a work in progress. Sorry for so much confusion in the post.
