If you want to learn more about the Skating Skills component, here is an old ISU documentary from +3 era which explains how you can recognize good skating. Unfortunately, I could not find a newer video about this component and even the old one is no more available on the ISU channel and has been uploaded by a fan who split it in seven 2-3 minutes long segments, so... It is as good as it gets, enjoy
