[CPAP] Struggling with settings

[touwmus]

I'm struggling with my CPAP settings; I have a Resmed Airsense 10 and after experimenting with full face mask i switched back to an airfit nose mask with mouth taping. I have been recommended settings in a previous post (see link). 

After that I went back to my sleeping doctor, he advised against the Autoset setting and turned me back on fixed pressure at 8.
In the meanwhile I turned my pressure up myself to 8,6 because i had the feeling i didn't have enough air.

My AHI in the period with these settings was in a range between 0,19 and 2,18. I attach my OSCAR result from one night with these settings. 
The problem is i wake up early, can't sleep further with the mask on and i don't wake up refreshed.

The questions I have:

1. Is this a good sleep quality?
   
2. Is the leak ratio ok?
   
3. Can my settings be optimized to obtain a better sleep quality?
   
4. Is there a trace of positional apnea in this graph?
   

Thanks in advance for your insights!

The leaks are too high, I'm not seeing clustered ca events but you're having some clustered uas and oas, I'd raise the pressure to 9.6cm for now and see how you feel-is your tape working or do you notice that it is loose in the morning, it could explain the leak rate...
