Here is a little info from the file
This is on the first page which shows the 2 sides:
The Wisdom Panel® Insights™ computer algorithm performed over seven million calculations using 11 different models (from a single breed to complex combinations of breeds) to predict the most likely combination of pure and mixed breed dogs in the last 3 ancestral generations that best fit the DNA marker pattern observed in Chichi. The ancestry chart depicting the best statistical result of this analysis is shown in the picture below.
This is from the second page which shows you the percent of each breed from the mixed side;
We have identified for you the 5 next best breed matches which appeared in the analysis of your dog's DNA. One or more of these breeds could have contributed to the genetic makeup of the ancestors indicated by the mixed breed icon. The breeds are listed by the relative strength of each result in our analysis with the most likely at the top of the list. There could also be a breed or breeds present in the mixed breed component that we cannot detect with our current database of purebred dogs.
I've attached some pics of the PDF
