Liza and Rika have had 3A's for years and it hasn't ever guaranteed them a medal or meant that they had the assurance of falling and still medaling. (Liza's had her 3A for SEVEN years and doesn't even have the assurances of getting out of Russia. Granted, Russia's women's technical content is astronomically high HOWEVER that hasn't been the case for the entire time, just since the 3A. Even the last quad, Liza's technical content was higher and it never guaranteed her a medal.)
In fact, none of Liza, Aliona, Young, Mirai, or Alysa (armed with their 3As) have even been guaranteed placements on teams.
Now, admittedly, some of that is the strength of their respective nations (especially Russia), but Liza T and Aliona could both skate clean programs with 3As and be outscored by Anna, Sasha, Kamila, etc. As for Alysa, she wasn't clean (but she landed three 3As which is what we're discussing) and she was beaten by a clean Daria (and would be beaten in seniors).
