Yeah, if anyone is going to voluntarily give up her spot it would be Felix. She is a virtual lock in the 200. She should probably just decide to focus on that. She'll likely be on the 4x1 and 4x4 teams. She's going to the Olympics, without a doubt. The only reason she still wants this chance is if disaster strikes in the 200. Tarmoh isn't famous and doesn't have the big endorsement deals so she probably needs the Olympic berth to get her big bonus.
Kersee has repeatedly stated that he can't favor any one solution that might benefit one or the other. BUT he doesn't want a decision before the 200 and that stance alone favors Felix.
Felix is a heavy favorite to make the team in the 200. By delaying the decision she has enough time to make sure she's on the team in the 200. She may decide that she only wants to contest the 100 if she somehow misses the 200.
Employee 1.1 or whoever it is seems to think that it's weird that the default is a runoff. But it has to be that way in case of an injury in the 200. If Felix pulls a hamstring in the 200 and misses the team then she would also be unable to do a runoff. If the default were a coin toss then the injured athlete's chances would still be 50/50.
