Yes it does, because technique = muscle memory => long time to become refined. Have you seen any skaters who start at 25 year old who are able to attempt quadruples? No, because at that age their body is already past its prime, and they are not capable of it anymore. The fact that Alysa Liu has the correct techniques now, only means that she has more time than any of her competitors to refine her techniques, it is not a detriment, and never will be.Teaching correct technique doesn't require a skater to be a certain age.
