We all know that there's an unwritten rule that rookie eligible skaters usually do not show up at their first Worlds or Grand Prix event or national championship and win the title (or medal) in their first try. It just isn't done in the super-charged, political world of figure skating. A new skater usually has to pay his/her/their dues with one or more seasons of solid programs before the judges pull out the kind of marks those skaters really deserve.
The late Carlo Fassi expressed his opinion on this subject a number of years ago. To paraphrase, he said, "If you're a young skater in your first year on the international circuit, you have to brace yourself for what's going to happen. You can skate a beautiful program, and you'll usually receive lousy marks because the judges don't know you and haven't seen you skate before.
Then, the next year you may compete in front of the same judges,
and you may skate a program that isn't as good as the program you skated last year, but you're an experienced skater now, so the judges will reward you. They'll remember the lousy marks they gave you last year and give you the marks you should have received last year this year."
