I don't know how many Zhou-naysaysers are aware that Vincent's training opportunities were very limited at Brown. Ice facilities were quite far from the dorms, and required driving back and forth several times a day. That not only cut into his ability to train, but also his study time. As he is in a demanding pre-med program, he was not able to do his GP events this fall because they were scheduled back-to-back during midterm exams.
Vincent has now taken a leave of absence until after the 2022 Olympics (a major reason he chose Brown, because few colleges would allow a leave of absence after just one semester). He will be fully dedicated to practice from now on.
What Hiwatashi supporters don't seem to recognize is that Tomoki is not anywhere near as consistent as a well-trained Vincent is. Tomoki can deliver a fantastic FS at one event, then is hit or miss in his next. He scored 227 for 5th place at IDF then only 207 for 10th at NHK. He had botched SPs at both his GPs. He was able to redeem himself with a squeaky clean FS at IDF, but had 3A problems in both segments at NHK.
