Kaetlyn will get higher PCS scores when she has more exposure before ISU judges and she can show more consistent performance.
And this is totally wrong.
Yes, Gracie is inconsistent on a seasonal basis. But she has consistently placed top 6 or better at Worlds/Olympics every year since her senior debut in 2013. That's a pretty good "big stage" record, better than any Canadian lady since Joannie Rochette left competitive ice. And Polina has placed top 10 at Worlds 2014, 2015 and Olympics despite her youth, and won 4CC last year. Polina's performances at US Nationals this year were breathtaking.
Osmond has had troubles in the past with her basic skating that could be traced to her injuries. She still struggles with inconsistencies.
Sure Osmond at her best can compete with Gracie at her worst, which is what we saw at 4CC. Can she compete with Gracie at her best? I guess that is the question.
She was not at her best at this event.
Her jumps are huuuuge and she is a far better performer than Gold. So if she is at her best, then yes, she can compete with Gracie at her best.
