does anyone know how to do the out of bounds dive glitch?

As far as I can see you just have to dive into the left corner on the first obstacle, where the obstacle meets the wall, and hope that it works.

I do do it semi consistently by Jumping left from the middle of the second most Marking From the left on the floor I also call the glitch Sand swim for short. sorry if this isn't descriptive enough I don't know how else to explain it. I spent a few hours trying setups before I got it.

ok thx!
