This twizzles did not get perfect score https://youtu.be/aREBn2rFtN4?t=135, sorry but I don´t see why P/C got perfect score and not Maia and Alex.
The synchro issues are tiny tiny, but against B/S in CoR I wouldn't expect perfect scores on twizzles. But it gives a reason for judges to nitpick since Ice dance is all about that.
However, I think they might get that 8.40 in America. Well if you go with the scores' logic meaning the scoring is about how you did vs this other team, they should easily be class of the field, even with C/L (who have good twizzles too by the way).
