The score received is based on what you did at the moment not a week ago. It was very obvious that gabby lost her balance and took several steps out of control, the other girl simply slipped over the line and they were penalized the same. A very obvious case of PC.The balance beam was about the same. The Olympic rule to allow only two gymnasts from each country to compete in the all-around is PC to, and does let the best one all compete.
You obviously don’t know scoring. Gabby was penalized over a point for her mistake. Jordyn lost a tenth or two.
