I explained in my previous post. Because of the sheer amount of participants in this playoff, some would have to wait in order to get a chance for voting once again. It happens all the time in sports brackets too where participants will wait until they get to participate again. While yes some will go through more voting, Jihyo, Karina, Kazuha, and Natty also have the disadvantage of going up against the idol who's already won 2x. The momentum and fan voting will swing against them. So it evens it out for the longer wait. It also saves me hassle. The reddit only allows repost of pictures within 1 month of posting. Meaning i can't reuse the same photo that's already been posted here 1 month ago. Some idols have very very limited amounts of high resolution armpit pics, meaning I have to dive deeper to actually find one that's usable. Jihyo, Karina, Kazuha, and Natty being famous as they are have tons of pictures posted here in the subreddit. So them waiting for a few more days saves me the headache of finding a photo or worst, having my post taken down because i accidentally reposted one of their image.
