What's the big fuss over WR though? There's only one Gold medal so only the player who is most on-form during the Olympics would take it. She would simply have to take down whoever she is matched with.
It would be an extremely honourable win for Ito if she is able to defeat two Chinese women in a row rather than hope that one gets eliminated by the other en route to the finals. The same goes for the Chinese women, wherein the gold medal is really only worth something if they manage to take out their greatest competitors themselves.
Imagine if Mima can take out 3 gold in XD, Singles and Team. TT world and China would go crazy
Team event she would need to win 2 singles and hope other 2 ladies can win doubles, massive ask but not impossible.
Absolute worst case scenario if Mima wins 3 gold and Harimoto beats Ma Long and FZD. Japan win 4 Gold to China's 1 the Men's Team
