oh yeah i am able to reproduce that – you might be right on the cause; i’ll look into it tomorrow.
never noticed because my strategy for that walljump is to hold back into the wall so that my head doesn’t go past center and then rotate and slowly climb, so i wasn’t buffering the first turn at all (only the second one). i think the way you’re trying to do it is nearly frame perfect at normal speed because you can’t be holding the opposite direction when you do it, so you’d have to push it at the very last moment otherwise you’ll go too far.
