I think people need to stop being impatient. This happens for most speedrun games. There seem to be a lot of new runners that don't really understand all that is involved. Veteran runners that stream to large audiences or WR being streamed and approved instantly is a pretty normal thing in the general speedrun community. I don't think its favoritism, it's more of why watch a WR that mods just watched live and can verify it was done legit. This "Instant" verification only happens with WR for the most part. Everyone needs to just be patient and their run will be verified soon. If you have to wait a week or two it shouldn't be a big deal. This is all for fun at the end of the day.
I would check out guides on youtube. Plenty of runners in the discord have made videos about it. There are different ways depending what hardware you are playing on as the fastest way requires you to switch to 30 FPS.
I've heard it's based on looking down and to the right while draining and looking down with a tight line to get there in time.
