The thing is judging from the current votes it does not necessarily translate to a strong 1 pick. That is the current top 9 might not actually make it to top 9 if it was down to 1 pick
I feel like Yaning might have a strong 1 pick? People might be voting her now because they really support her and realise MNET is just evil editing her. We believe in the Lord Fuya supremacy
Another might be Ririka? The top 3 J trainees are the 3 easy votes because they have screentime. Yes Hikaru has less screentime in the past few episodes but her first performance already make it easy for her to be an easy pick for 3J. Ririka however does not necessarily has the screentime the rest have. Many supporting her might be from NiZiU or something. Whether or not she is a true 1 pick (regardless of nationality) I'm not sure. Like I'm pretty sure Shana only got rank 4 because of the 'I can't reach the high note' screentime.
