I thought while I was doing Legacy runs, I might as well try and see if I can improve my Default record. And so I did! Althought just by 0.002s, so nothing major. However this time I try to (or more get lucky) to get as little height as possible after the platform bunnyhop (the one after the Wall Boost). It happens somewhat rarely but allows you to just straight up curve under the next platform without needing to ride the wall to lose height first. The ending wasn't the best but good enough.

I also noticed strangely that sometimes when you jump towards the end you will get stuck (at least when you use Manual LRF) on the edge and the Wallrun Timer will tick down. If you press Jump it will give you a Wall Boost, so it could be theoretically optimal to get a "Wall Boost Storage" right into the end, but I don't know if it's even realistically possible or even faster. But just writing it down here so I don't forget about it if it turns out to be useful somehow!
