AXG Sleep Diagnostics?

I think it's time to call it quits with ST-A and go back to my old VAuto.  I'm getting nowhere. These leak rates are just absurd and uncontrollable.

I found my old ResMed AirCurve 10 VAuto SD card from my machine I had until mid-2022.  I had another VAuto machine after that until 40 days ago, but do not have that SD card unfortunately. I know several here said they were curious how things looked on the VAuto. This is the best I could find.

OSAs were way more prevalent using the VAuto vs ST-A unit I have now.  Sometimes overall AHI numbers are similar among the machines.  I think it is quite obvious whatever I've done so far just hasn't caused any real improvements.  I am not sure I've felt worse than I do on the ST-A regardless of what numbers/charts show.  My diaphrahm muscles are so worn out.  Fatigued like crazy.  My muscles just don't feel like they're recovering from sleep.  I am not sure where to go from here honestly.  It's pretty obvious I have some serious sleep problems one way or the other.

I wanted to see how it felt to use my old VAuto machine compared to the ST-A.  There is surely a difference in the breathing muscle fatigue being less using the VAuto.  Way more tolerable at similar pressures.

Attached is a screenshot of last night's session.  I'm at a complete loss on what to do to control the mask leaks.  They just get worse.   Maybe I need to go back to the Mirage Quattro.  Apparently, the Vitera is a failure.  The DME thought that mask would be the 'one.'

2nd night using the deluxe chin strap.  My AHIs on the VAuto aren't as low as the ST-A Machine, but I feel much more awake the few days leaks have been reduced greatly. First night with no Large Leaks all night.

Still having a fair amount of apneas/hypopneas which makes me wonder do I need to adjust pressures to compensate or do I truly need the ST-A machine.  I got my O2 meter back today from the company (repaired) so I'll see how the O2 stats look when the mask is worn with a better seal.  Should be interesting to see how low O2 goes in presence of these clusters of apnea/hypopnea events.  All seems to go good in the beginning and later in the night I experience issues. 

I assume 16/8 is not a high enough pressure to resolve the events. Do these events indicate I may truly need the ST-A machine since my AHI numbers were so much lower on it? Again, it did not correlate to any feeling of better energy/sleep in any way.
