Is there more information about this? This sounds super painful to juggle all at once. How do RTA runners get 100%? This sounds almost unapproachable to route. The only thing I can imagine right now would be "follow RTA, but with savestates" then hope one day someone figures the rest out.
I'm assuming you are asking about routing a potential 100% TAS? This would truly be an ordeal. We need just under 90 kinstones total, and it can't just be any kinstones, we need a fixed amount of each shape. Currently the RTA route does a trick to go to a spot OoB after getting the Ocarina which lets us farm at a spot to collect all the kinstones we need VERY fast, this is quite out of the way and likely wouldn't be done by the TAS as we can now just collect kinstones we need along the way. The biggest pain in this trick is that the kinstones are completely random, with the kinstones we really need being the rarest, and in order to get enough of them we often times have to get many wasted extra of other shapes we don't need more of, along with the fact we don't know what shape we are getting (nor what colour either since this is all happening off screen) unless we waste time opening the kinstone bag in the menu to check our counts. Particularly bad farm RNG can result in losing 20-30s.
