Calculating The Dosage Profile

PEDIGREE

It is necessary to begin with a 4-generation pedigree. Let's assume our subject animal is multiple G1 stakes winner Cryptoclearance. Here's his pedigree:

SIRE GRID

Now that we can see who the sires are, and can determine which of those are Chef-de-Race sires by consulting the current Chef-de-Race list (a link is available on the previous page). Next, we need to determine how many points are contributed by each. It is helpful to visualize the sires grouped by generation. To do this, I insert the sire names into a graph such as this:

By adding up the points earned in each category, the Dosage Profile is created. In the case shown above, Cryptoclearance's profile is (13 - 19 - 22 - 1 - 3) which is the sum of points earned by Chef-de-Race stallions in each category.

And that is how the profile is calculated.
