Well you'd probs be best off asking one of the top runners in the discord, they are usually quite quick to respond. From my limited understanding you can get this:

• there's not really a guide nor strong consistent method to it (don't fully know why) but it has something to do with the precise positionings, making it kinda inconsistent. The most succesful method is the one where you walk backwards while uv-ing the stairs in front of you and try to drift to the spot where the side-fence stops you.

Don't take this as an explanation nor as pure fact: I have to this day not succesfully done the trick, nor do I now what specifically makes it so inconsistent: what I do know is it takes a lot of effort and grinding, and some luck on top of that

Hope this aided a little, and please: go to the discord and ask somene better than me

I mean, in the BotW extensions there's a section named 'kork collections', were you can run for all koroks, 100 koroks or 10 koroks. I'd like to see the catergory return like that, it leaves some more options open for people that don't want to purely grind all koroks. Anyway, it woud seem weird to not have an extension here that exists for BotW and of which barely any mechanics have changed. I'd guess for the 10 and 100 koroks the run might even be faster then its BotW counterpart

(Just suggesting this because I've seen a great deal of popularity about this)

Would it be possible for a category extention where you have to crucify a korok as quickly as possible? In my mind that sounds kinda akin to the butter on dog category from BoTW and well, I've seen plenty of clips of people doing in on yt already, so there's reason to assume people will be interested. Additionally, I assume the routing will be slightly different from the great sky island routing and from the any% run
