well, i think it will be very interesting when everyone returns to competition. maybe those who want to see ultra si go away will get their wish...
Shcherbakova was doing quads prior to her leg break in summer of 2017, she missed most of the 2017-2018 season, and by the fall of 2018 she was doing quads in competition. Additionally she didn't exactly appear to go through some huge puberty swing and she was 13 at the time, which is a common age for puberty, and was far more restricted in her ability to exercise at that time since her leg was broken.
