Tin Foil time. I wonder if the CCP will produce false positives for athletes that would cause China to not place well in events. I trust Japans government to not do that in the summer games, but China is suspect.
And if 1 doesn't think this could happen, look at the Russia doping scandal. It wasn't just 1 or 2 athletes, but teams of them. Followed by the official testing centers being in on it and so on. Especially since 1 can have zero symptoms and in this day and age, no one smart would question a positive test.
And so they don't make it too suspect, they won't just have the top seed test pos the day b4 their event. They could do it 1 week prior and that would mess with their mind and performance. So still an advantage.
Personal Example:
When I don't lift for 1 week, all my lifts go down slightly. And not lifting because say I'm on vacation, not because I'm sick or injured. So I'm not at the top of my game. I can imagine that non weightlifting events would be similar, like skating, skiing, bobsled, etc...
Then add in the athlete cannot leave their room, so stuck in a small room for 5 days or longer if the protocols are 14 days or what ever. Missing practices and such. And add in lack of eating their normal diet. But I'm sure their coach would drop off what ever food is needed, so there should be a work around for this issue. Then the mental aspect of that athlete or any they've been in close contact with who have to test or need to wait and isolate until X days have passed.
So the virus that China weaponized, can still be used.
