And your comment is why I lost respect for those judges who probably agree with you.
You’re letting her previous performances color your opinion of what should be a fair and unbiased judging of this one performance and this one category in a vacuum. It’s originality, she was more original in her performance than a lot of other breakers, regardless of her skill (which is a separate category they rate on). I would have hoped she would have scored at least a couple of points there and just 0s on all the other categories.
I agree with your BM comment though.
Sorry to break it to you but it factually IS about originality. That’s one of the categories the judges for this sport specifically rate on according to the olympics, or should at least, it’s obvious they didn’t in this instance.
Here’s some sites that specify originality is one of their 5 scoring categories.
