While I agree, keep in mind that Czisny has been around even LONGER. She was competing during the height of the Kwan/Cohen rivalry! She competed senior nats since 2002 (?), didn't win her first medal until 2007, and actually won in 2009.
Not everyone peaks at 16 or 17.
Exactly! I think as Ashley gets older and matures she'll realize what aspects of her skating she needs to improve and work harder, she clearly has the drive and has already made clear improvement.
