Besides Patrick, Carolina has gotten an enormous amount of love from the judges over the years, more so than Yuna has probably. It may be that the judges were willing to forgive Carolina's many lapses because they really love her skating skills.
Of course, Yuna has gotten alot of love from the judges as well, but I think it was not so much about her skating skills as much as the fact that she is so very clean. Judges really love clean performances and suddenly the GOEs go a bit higher than they ought to.
Judges also love Dai as well, but again, I think, for another reason. With Dai, I don't think it's his skating skills or him being clean that they love but his magnetic charisma. If you are as magnetic as Dai, then your PCS goes up just that little bit more.
So, if you have Patrick's/Carolina's skating skills, can do your performance clean like Yuna does with Dai's magnetic charisma, that probably for ISU would be the perfect skater.
