The data you sent me includes Feb 24th to Mar 9th. It looks like you were using a nasal mask until Mar 5th and then switch to the F10 on Mar 6th (that is when machine setting changed from nasal to FFM).
While using the nasal mask I see you were using min EPAP 8 cm, max IPAP 26 cm, PS 5-12 cm. Leaks were definitely an issue with that mask and settings and it appears there are periods of mouth breathing with large mouth leaks. Below is an example of one of the worse nights. Some of the leaks and mouth breathing that night were so bad they reduced your flow enough your machine shut off because you have smartstart on (1:45 -2:00), I would turn this setting off.
After you changed to the FFM you tried min EPAP 6 cm, max IPAP 30 cm, PS 4-15 cm. This was your best night of data.
The next night you tried limiting max PS to 9 cm (same min EPAP and min PS) and this was your worst night AHI wise.
