It depends on what you use the data for...I used it just to show folks that breeding is important when looking at the Derby. If you use that to "prove" that only grade one winners make good sires then you have to figure in the predisposition of breeders to breed to same instead of horses with lesser records. In other words, if I'm a breeder and I want to breed a class mare, I need to understand that this data is effected by opportunity...Ole Bob Bowers
might just produce a runner despite his lack of a grade one win. But, if I'm looking at Derby horses to pick a winner, it doesn't matter so much about why the data is what it is...it just is! Again, some no-name stallion that never broke his maiden COULD produce a winner but the likelihood is small BECAUSE he wouldn't have had the opportunity to cover a top mare! So, as a bettor, I don't care so much why the data is as it is...I just care what it is!
