not to tear down a teenage athlete but because if she doesn't get called on it means she's unlikely to fix it,
Easier said than done.
Skaters can only do what they can do.
There's always room for improvement.
But rotating 4 times in the air is cutting edge for what the human body can do using blades on ice. Especially female bodies, and it only gets harder as girls mature into women. Time is not on their side when it comes to jump rotation.
It's not as simple as just knowing what they want to achieve and working hard to achieve it. At the limits of ability, physics and physiology will have more impact than input from technical panels or judges.
Or even from expert jump coaches.
Which isn't to say skaters shouldn't aim to keep improving anywhere they can, to maintain an edge against their top competitors.
But "fixing" an extremely difficult feat to be perfect instead of not-quite-perfect is not something that can be done on demand.
And not a matter of either/or. Continuing to improve doesn't mean that there won't still be room for even further improvement in theory. The best quad anyone actually achieves will likely still fall short of the platonic ideal.
