Let's take a non-bias look into what Ina's doing right and Kiara isn't (in the live viewership department). I won't be diving into some aspects such as their voice, or their personalities, they are undeniably major factors yes, but let's just look at them as two streamers with different sets of skills.
> Ina's stream schedule is almost always consistentConsistent timeslots always bring in the best live viewership, because the fanbase know exactly when they can tune in, and they can always leave that timeslot free for her. Moreover, it helps Ina build up her core fanbase more and more, it might be slow but it sure is steady.
Kiara has been showing to hop her stream timeslots all over the place, one week she seems to favour the yuros, the next week it's better for the SEAnigs. She lost a portion of her live viewership (mostly SEAnigs, and OCE) and her core fanbase as a whole by inevitably shifting her schedule after moving back to her home country.
> Kiara plays long ass JRPGs on streamLong stream length does affect live viewership because at the end of the day, only her core fanbase will stick from beginning to end.
Not saying debuff games don't affect Ina, but with her consistent timeslot, anything not some jank ass game like Wah-nderful 101 will bring her the views (though we have to admit she has been playing some typical buff games). And we haven't even talked about the art streams yet, which are the ones that can easily pull numbers, because people always hop in to check the progress.
Also a little tiny buff for Ina right now is also the fact that the work for her MV Violet is assumably finished, but that probably doesn't mean much right Takos?
