One thing I was thinking about this skip last night, is with other out of bounds skips, your going through the OoB area. Like going through a solid wall, falling through a solid floor, those skips involve clipping out of the map and then clipping back in at a later area. This "trick" we are talking about is a little different, because your not getting to an unloaded courtyard and appearing on the other side, your just getting there.

Just a thought on my part, I'm still very new to outlast speedrunning and speedrunning in general, just thought I would share.
