RE: Help with settings
The screenshot with the closeup respiration from 1/21 shows perfection and a respiratory rate of 15.0 BPM at 22:42-22:43. The next one shows a respiration rate of 7.5 BPM and some flow limitation at 22:54. The session information is cutoff so I don't know what changed, but the first one is only a 6-minute session. Anyway, your minute vent and tidal volume is up and not particularly alarming. We still don't know the source of flow limitation or slow respiratory rate, but maybe it's not a problem. You should ask you doctor if that is anything to be concerned about.

RE: Help with settings
So I decided to buy a pulse oximeter to see how my oxygen levels and heart rate were when I am asleep. Not sure if it's good or bad or average, just wondering what your impressions/analysis might be. I woke up around 4 am and removed it because my finger was a little sore. My heart rate will probably seem low to you, but it's not out of the ordinary for myself, it's usually in the low 60's when I'm relaxing at home, but it seems to change a lot when I'm asleep. 
The leaking seems under control and my AHI is pretty reasonable.

RE: Help with settings
Your median oxygen saturation of 93% at night is not very impressive, and a normal range is 95-100%. My own oxygen saturation rarely falls below 97%. Values below 90% are considered low and the Medicare guidelines would require desaturation to less than 88% for more than 5 minutes. You might want to include a dotted line at 88% to see where you actually reach that threshold or locate the statistic for tme below 88%.

Your doctor is the most qualified individual to look at your results, perhaps use arterial blood samples, and determine if there is a need for treatment. At this point, I'd consider you chronically below average during sleep. An interesting correlation on your chart is that pulse rate rises and SpO2 drops during the periods where your expiration time increases. It would be interesting to see the respiration rate chart as I suspect this also correlates to times where the respiratory rate drops.
