I think this will 'time off' the ice will aid skaters like Kostornaia, Tuktamysheva, Shcherbakova and Trusova who have triple axels/quads and have had those jumps and competing with them for awhile vs. skaters that are just starting out trying to learn those elements.
But real question for people super familiar with elite level training - how much will this really affect them? It was right at the end of the season, I believe the season itself was shut down 7-10 days prior to Worlds so skaters going to worlds were full on training (unless they were sick or injured); after Worlds we usually hear about skaters going on vacations, the ones that have school are focusing on end of year exams - so how much does this really inhibit their training routine because from years past it seems this happened in what's usually a lighter training schedule for the skaters.
