Been talked about a lot in streams but never timed so here, doing the lever skip is roughly 3.5s over doing lever optimally. You do this by doing a mini boob at the bench room, fluke so you can wings again, and then walljump, wings and (optionally but preferably in my experience) dash in the wall to the left before you walljump up to the transition above. Dash slash on elevator was tested and didn't seem to save any time. Retrying the boob into walljump wings is ~2s so if you can do it within two tries it's still good.
