So it turns out there's an exploit on this level, I don't know if Dadu used it in their record but I'd bet not. As you can see, if you reset normally you spawn parallel to the barrier. But, if you're ramming a barrier when you reset, most of the time the game spawns you diagonally, giving you a much tighter turn. Also I've found it's optimal to clip the 3rd barrier, doing no clip builds up too much speed and any other clips aren't as efficient.
