I noticed the leak rate would go up a bit before I would wind up waking (slightly) n changing position ending in disturbing my sleep. Am wondering if that has anything to do with mouth breathing? Using APAP I mouth tape because air starts leaking out of mouth later throughout night (entering REM? not sure) if I don't.
Your muscles are relaxing in REM and your mouth is either ballooning from the pressure or escaping from the sides of your mouth. I'd target a 95% leak rate as low as you can get it before making any other adjustments. Each of the leaky periods. especially the sharp spikes are likely causing arousals and fragmenting your sleep.
