If it is spiky like the Rockies and jumps up and down a lot, then it is probably a mask leak.
I think it is because the mouth opens and stays open while the mask will flutter sort of. Different than the lips fluttering.
Thank you for that explanation regarding how to spot mouth breathing via the leak rate graph. Very useful
