Idk if this is common knowledge but I thought this was an interesting take on level 3. Obviously not as fast as the floor clip but seems faster than the tree, so could be a nice medium for people who want something a little more consistent than the clip. As most things in this game the climb is a little fidgety.

I think it's about the same speed as the optimal tree strat, my best wall climb lvl 3 is 5.80s and my best lvl 3 with the tree jump is 5.58s

Probably so, and considering how finicky and position-dependent the wall climb seems to be it probably isn't ideal in most cases.
