You are underestimating all the Europeans:
There is Kimmy Repond

who skated 170+ at all three of her events, Lorine Schild

who is the best French lady and scored 179 in Juniors. Then, the girls from Finland

who are hit and miss, but, can beat the two Americans, when they are on. There is an Estonian

girl. Josefin Sweden

can score 160+, even with an easier technical abilities. The Austrian

local fave can also score over 150. Julia Lang from

scored 160+ recently. The Italians

can also score over 160. I have no idea who will win. I think a score close to 180 gets you gold and a score over 170 is necessary just to be on the podium. But, it wouldn’t surprise me to see 1 or 2 Europeans on the podium. Especially, Repond who is so consistent and Schild who placed well at her two Junior events.
