For ladies single, it's something else because certain body types tend to do BETTER - rotate faster specifically. Then there's the height -- shorter = lower center of gravity & more stability. Mirai's latter body is not ideal in that she's thicker than she used to be and carries more weight in her bust/shoulders. This can be said for a lot of skaters who were basically destroyed by puberty. (BTW - I'm also of the opinion that skaters who actually learned proper technique tend to survive puberty much better than those who relied on their super skinny short body to land jumps.)
I'm convinced that if Tara Lipinski's hips were half an inch thicker, Michelle would've won the gold in Nagano.
