How the hell does the current Youtube comment system work?

I have a bunch of 3+year old Youtube accounts with no strikes etc, I use them to rank my comments, like my shit and so on, but I can't seem to rank my comments, they always go down, unless the video im posting at doesn't have many views and comments. I managed to rank a comment on a video with 20.000 views recently posted and about 300 comments and it's still holding up there so not bad, but I need to rank my shit on the 1+million view videos with tons of comments, and i cant, even if my comments has more likes and more replies than a lot of other comments that are at the top (and some of those channels have less subs than mine). I just dont get it.

Videos getting lots of views and comment activity will juggle top comments. You will notice this when logging in and out of different accounts on same video. You are better off getting lots of new accounts and doing comment replies on all top comments. I do this with a bot I had made and it works better than trying to rank your own.

I heard they were going to take it back to the old comment system as the current one was too confusing for the commenters.

Thats nothing you can change.I saw many times comments with higher amount of likes being nowhere where comments with activity where on top
