Short answer..
7 min. 8 max
modified this after seeing on my PC, phone was not seeing the OA events, which seemed to happen closer to 8 cm.
I am wondering John, did you get prescribed possibly 8 cm, but they set you up with EPR 3 which would drop to 5 cm pressure during exhale?
If that is the case, i would adjust as follows....
8cm pressure, no EPR and see how that goes.
The obstructive apnea events are still happening certainly nothing serious in my experience.
Keep an eye on your time in apnea and how you're feeling rested or not.
The CA events may go up as you are raising some of your pressures which is why I was originally suggesting and anticipating that and dropping just a bit on the max pressure.
Seems like you have a pretty stable sleep but just know that it's not likely that it can stay that way all the time they're always seems to be bumps in the road at least in my experience.
Hopefully you can stay away from the coffee later on in the day as that could even affect you for sleep but everybody's different with that.
Let me know what you think?
