Some interesting observations from these broodmares with very superior racing indexes. First, Champions usually have a racing index of 25 or higher and this is the point where the "law of Diminishing returns" sets in. From there on as the mares racing index increases it increases the likelihood that she will "breed down" from her own index. As you can see the top five mares all bred down from their own indexes. Only Gay Charm the dam of Einstein bred up. The problem is that Gay Charm raced in Brazil and her racing index is only an estimate



Another important factor is that once regression has taken place in the family a resurgence can take place, that is why Mr. Sidney by Storm Cat and First Defense by Unbridled's Song are excellent Stallion prospects. On the female side the same hold true for Mi Sueno.
