In the room with the elevator that only goes up, it will make you jump a little higher if youve been on the elevator for a little bit, so if you time and space your jumps so the elevator barely moves before you get on it, and make sure you get on the rightmost edge, then walk forward for a bit, then time a boosted jump really well, itll save a little less than a second

But the the first place time is 1m 38s?
