So, first thing first. I'm using Airsense 11 with EPR 3 full time, pressure 12~20 now.
Two Main issues I'd like to solve:
1. N30i with frequent leak/unconsciously pulling off the mask issue. That'll bring subsequent awake, and disturbing sleep.
2. Smart watches reporting awake during night - I know it's not as accurate as EEGs - but the time it shows conforms with the data OSCAR/Airsense is reporting(there'll be multiple events when "awake" logged by wearables. Sometimes I'm awake enough to memo down time I'm awake, and it also confirmed the fact. This issue will happen independently, even without any leaking.
Solutions tried:
1.a Already tried different looseness/tightness to N30i, am using taping technique from temple to chin on both sides of face currently.
Especially this one: https://www.apneaboard.com/wiki/index.ph..._Jeffy1958
It still cannot eliminate enough leak though - when the leak happens long enough, I'll be awake in the next 10~20 minutes.
2.a
I have no idea, I tried increase pressure every 10~20 days, but to this day (65th day), it's still not working well.
Sitrep:
In the first 20 days, I kept my pressure at 8 ~ 20, and this is what I got:

Apparently it's as ugly as it can be. One typical day during this period:

After that, I increased the min pressure to 9, this is what I got:

You can see that it's only marginally better. Subjectively, I did not feel any better compared to previous settings. The only thing about the pressure increase is that I have slightly lower AHI.
So in the last 10 days, I tried to significantly increase the low pressure to 9 to 12 - very aggressive and not recommended by the apnea wiki - but it yielded good results.

We're observing much lower AHI.
However, the awake issue is yet to be resolved.
One typical day, where I fell asleep at 01:46am, and woke up involuntarily at 06:15:

During the sleep, the watch reports from 0238~0327 I'm awake, and from 0428~0501 I'm awake. I DID WAKE UP and able to memo down one awake time, which is 0450.

For the 0450 awake, I suppose it's due to a major leak and multiple CAs before 0450, causing me to awake.
For the 0238 awake to 0327 awake, this is the graph:

TBH for my ability, I'm unable to pinpoint my awake reason during this time period. I can only observe the pressure gradually increasing, and multiple OAs appearing - but the major leak only happens after the watch reported awake period, that means it's not a mask fitting issue. I'm using standard autoset algorithm.
This is from 0428~0501 reported awake period:

I can't pinpoint the issue here either - besides the apparent 1min 40s leakage, the pressure is stable and the leak rate is also stable. However there's a lot of CA events happening, with frequent Flow Limit - it also conforms with how my watch reported, that is I was semi-awake during this period.
To recap my questions:
1. How can I do to improve the random / short, but significant leakages, that'll increase events and ultimately make me awake? (Taping already used as previously mentioned in the beginning of the article. Nasal cradle size is also measured/tried between s, m, sw.)
2. For the supposedly awake without leakage - I've raise two examples above. How do I solve them? Will increasing pressure AGAIN from 12 to something like 12.5(past 10 days avg) or even 15.3(past 10 days 95% pressure) likely to solve this issue?
Thanks so much, kind netizens from apnea board!
