This web page will show Graded Stakes Winners from around the world that have a similar pedigree to your proposed mating. Based on the concept of "Dig for Gold where Gold has been found before", it makes sense that your breeding plans should look to replicate pedigrees of champion runners and the analysis should look at the entire pedigree.

Results List - This list will appear on the left side of the page after you click the "Match Similar Pedigrees" button. It shows Graded Stakes winning horses that have a similar pedigree to your proposed mating.

Results List Columns:
CSI or "Common Similarity Index" is a measure of how close the pedigree of the Graded Stakes Winner matches the hypo-mating. In general, values above 18 indicate a strong similarity. As a rule of thumb, if the results list shows 4 or more horses with CSI of 18 or above, it is usually a good mating. If it shows 2 or more horses with CSI above 20, it is usually an exceptional mating. (The Results List is sorted by the CSI column, so the closest matches will appear at the top. )

E is for "Exact" matches - this column shows a count of the number of ancestors in the 5-gen pedigree which appear in Exactly the same position.

A 20/20 Mating:
A 20/20 mating occurs when a pattern has two or more Graded Stakes Winners with CSI values above 20. This indicates that this pedigree is exceptional as there are at least two superior horses with a very similar pattern. In most cases the stud farm will offer special incentives for the breeder to send their mare to the selected stallion.
