That's why Russia shouldn't send three quad/3A girls to the olympics. Very unreliable.
It's much better if they send at least one girl with no 3A/quad, but with very high (GOE PCS).
From what I'm hearing about today's practices, Alina or Evgenia could have become world champs if they were in shape.
Shcherbakova's practices are rarely representative of how she does in competition and based on her SP with no quad or triple axel she scores quite well without them.
