True, but no one has addressed the issue of under-rotation of the 3T in her opening combo. It's quite surprising to see scores from both the negative and positive sides of the spectrum. One judge gave a -1 while another gave +3. I don't know about Yuna's combo but as far as the case for Adelina, it was kind of obvious she dragged her foot from a under-rotated position - even by looking at the slow-mo on TV.
I'm still finding it hard to swallow that they allow benefit of the doubt for wrong edge calls. It's like ISU is discouraging the correct use of edges, which makes a lutz jump differentiated from a flip.
Also, I'm all in for the justifications evangeline has mentioned. Even rugby, considered as one of the most roughest sports, has TMOs before awarding a try. During this session, 4 or 5 technical analysts are in a separate room away from the field. They communicate with the referees on field and actually discuss whether the try was legitimate or not, using at least 5 different camera angles. And all of this is broadcasted on air, for the audience to see - with the referees names and faces as well.
