The KEY FACOR has a tremendous impact on a sire’s graded stakes production, as well as his overall production of all successful runners.
In fact, stallion managers should make it the #1 criteria when selecting or approving potential mares.
In order to show how big an impact the KEY FACTOR has, we’ve chosen a wide range of sires, older and newer, and show their production of graded stakes winners from those foals that had the KEY FACTOR, and those that did not.
The results for those sires follow, both individually and cumulatively, and the results are amazing.
