So the current roster is 54 Trainees, 18 per group. The next elimination will cut it down to 30 trainees, which would lead to 10 per group
Most likely the next system will be 1 pick per group. If that’s the case, it’s likely there will be a top 18, 6 per group, for the finale (which makes sense cuz half of 18 is 9, aka how many will make the team)
So if there is a free for all vote towards the finale, even if all the K trainees are so popular that they every finalist from K-Group makes the final lineup, it would just be 6 at highest, meaning 3 of the J-Group & C-Group will still make it
Overall, no need to worry about 7K2NK, 8K1NK, or 9K0NK. Though those were unlikely to happen anyway cuz the top girls from J-Group & C-Group have strong enough followings to solidify them in the final top 9
Personally still hoping for either 3K3J3C or 4K5NK, 5K4NK is cool too
