The judges are experts in this field. They know this shit more than I/you do. Case closed.
Stuffs like this happen in other gymnastics competitions, including the Worlds. I can’t see why it’s so unacceptable that Japan appealed. They didn’t threaten the judges or whine like babies. Japan presented their case, waited for the results, and hoped for the best.
Put your heads up, guys. Accept the results. That’s how true winners do it.
