What makes breeding and pedigree analysis so difficult is that there is no one"super gene" that makes a great horse. There are not just many genes involved but many combinations of these genes. As Mendal showed, they resort themselves every generation. What this study does is open a window into the mDNA of these royally-bred horses to see what they got. It by no means claim to be able to give a precise prediction of a horses ability or point out the next "super horse". What is does is show a correlation between a few genes from the dam and performance at different distances. Every little bit helps.
