Is he kidding????
Posted: Thu Mar 06, 2008 3:51 pm
How about the below from Windfields Farm Web Site....Two questions....
1) Are they changing the system because they don't have the data? Werk uses a stakes winning population only, not the complete data and I know that they did a similar change with Hat Trick earlier in the year because Werk ratings dont collect enough data from Japan so the figures that Hat Trick was generating were bad. By the sounds of it they are doing the same here.
2) Machiavellian is by Halo? Are they kidding? What self respecting pedigree analyst would make such a mistake?
Change In e-Nick Rating System

Some changes have come about recently with respect to the Werk e-Nick Rating system and specifically, Best Of The Bests (Ire). We would like to share with you a letter from Mr. Jack Werk regarding this change.
"Dear (Windfields Farm),
We have recently made some changes in how our nick rating system treats stallions in descent of Machiavellian, and because Windfields Farm stands his son Best Of The Bests, I want to let you know how this will affect his nick ratings.
Our nick rating system gets input from a sire-line analysis that is crucial to the accuracy of the system. Among other things, it prevents a mare from say, Mr.Prospector line from a getting a nick rating based on her descent from Raise A Native. Years ago, Mr. Prospector emerged as a distinct sire line, both in terms of the number of stakes winners that represent him and in terms of his distinctiveness from other branches of Raise A Native. So at that point, we included in our system a sire-line input that prevented Mr. Prospector line mares from being treated as Raise A Native-line mares.
Within the last year or so, we established a similar sire-line input on behalf of Machiavellian. At the time, compelling arguments could be made for doing that based on his performance in Europe. However, having monitored the ratings for Machiavellian's N.A. based sons, STREET CRY and BEST OF THE BESTS, we have since realized that we overlooked an even more compelling argument.
Because most of Machiavellian's opportunity has occurred in Europe and because opportunity there differs markedly from the opportunity Best Of The Bests and others are going to get in North America, we concluded that nick ratings for Best Of The Bests would be more accurate without that new sire-line input. Therefore, we have removed it from our system.
This means that nicks for Best Of The Bests may go back as far as Halo as a basis for a nick rating, rather than being limited to assessment on the basis of descendants of Machiavellian. In fact, it is possible that those ratings that go aback to Halo will be even more accurate for North American breeders than the ones that are based on Machiavellian. Only time will tell. That's the limitation of any system that assesses nicks.
Most importantly, this change will provide breeders who have considered Best Of The Bests in the past to have another look in the light of the broader perspective represented by this change in our approach to his nick ratings. In many cases, they will find new grounds for an interest in Best Of The Bests, not to mention the fact that I think he is going to become a smashing success in Canada.
Kind regards,
Jack Werk
