This is honestly the most consistent method I could find. You basically run until the first camera transition and wait for the hunter up top to move in position to drop down. Use its footsteps and roar as audio cues. The roar indicates it's about to jump which you should be moving at this point.

Just showcasing the consistency of the waiting method and trying to get the other two RNG outcomes where you can run straight up without issues. It only happens twice in this video, but the way I'm able to know what hunter behavior I'll be getting is based on the noise it makes when I enter the room.

You'll hear it roar then begin to run (or even just start running) as soon as the room loads which means you have to stall for a bit. There are rare instances where you'll hear the roar, but the movement is delayed (2:16), or the hunter will perform the instakill attack (1:46). It will take time to be able to identify all these different behavioral patterns, but I find it's much more common for the hunter to rush towards you as opposed to giving you a free pass up the stairs.

So, I would advise to pay close attention to the sound of the hunter up top since he's the main threat.
