Clydesdale is most certainly less indicative of “lameness” than the same (6 mm) in a 200-lb. miniature horse. In 2014, this size-dependent factor was accounted for algorithmically. However, the standardization, instead of being based on size, is based on expected normal vertical movement. After all, it is not really the size of the horse that determines its amplitude of vertical...
