Analogy #1: Fantasy football is a major source of entertainment in the United States. Fantasy football owners form leagues and draft teams who win or lose based upon the performance of professional NFL players. Drafting the football players is very important for fantasy owners, and they seek help from published magazines. Based upon their own opinions, these magazines rank the NFL players so that fantasy owners may draft wisely. In practice, players get hurt or the fantasy owners may have their own opinions about how good they really are. Thus, the fantasy football owner buys the magazine, then adjusts their ranking of players to suit his or her own tastes.
Likewise, "The Primer Report™" ranks the yearlings and fully expects customers to adjust the list. Customers may prefer one stud over another, for example, and thus bump one yearling on "The Primer Report™" list above another. Customers may also either really like or dislike a yearling in person, and this factor might also affect the yearling’s position on "The Primer Report" list.
Analogy #2: You move to a new town and need to buy a house. Rather than stop at every house with a "for sale" sign, you might visit a website and screen for important variables like number of bedrooms, proximity to the interstate, price, and so on. You would rank the houses on paper, then visit them in person. A house may look great on paper, but, when viewed, might have questionable features. On the other hand, a house that seems mediocre on paper might suit your needs to a tee when viewed in person.
By comparison, "The Primer Report™" is meant to rank the yearlings based upon variables that helped dictate final sales prices at past auctions. Equinistics LLC has whittled down the number of variables that typically affect final sales price and ranked the yearlings for the 2008 sale. Customers can move yearlings up or down the list after seeing the yearlings in person.
