I researched and read all the articles, and it sounds like it's more of an initial edge-saver than a glide-increaser. To me, it sounds as though the liquid helps increase the life of the blade edge for the time that the coating actually lasts. It does nothing in itself to increase glide. The equipment manager in their video likely sharpened their skates with a shallower hollow. A gimmick if you ask me. If anything, it only lasts a short time before it is worn off the blade edge.
