RE: Maybe I have apnea, maybe not, are all sleep doc jerks?
Some musing below, cathyf, nothing surprising to you I'd guess. This post was begun after reading yours that it refers to. I haven't checked back to see whether others have (as is likely) been more helpful.
Re your overall view for 5/1:
I see in my FR signal the same attenuation levels as yours from very large leaks during those episodes near 0150, 0250 and 0440. I strongly suspect those periods for you are another manifestation of positional IFL--probably from one or more of supine positioning or other idiosyncratic position, tissue or phlegm impediment to airflow.
Your variations FR, I, E and RR support thinking The.5 level of FL at 0255 is correct in that fuzziier FR curve (larger leak) segment just prior to 0300.
Inspiration time shows you working hard to breathe enough air--don't know how you have withstood that so much of your sleep time.
The smoother, almost invariant FR curve shape, in the attenuated curve after 0300, explains to me the lack of FL signal--the signal trigger, airflow drop, is lacking. "No changeee downward, no trigger", so no FL flag. There is insufficient change in RR/duty cycle, amplitudes, wave shapes, ventilation, the factors SR and NIH cite as the contributing co-indicators of flow limittation.
Re one zoom (your third image, same sleep session):
What amazing uniformity--the time after 0130, even where centered at about 0340. The lack of mask pressure suggests to me that after 0130 you are breathing almost unaided, or even handicapped by PAP, with wind blowing in your face.
Constancy of high leak--no outliers--in leaky stretches along the Leak curve did raise a question in my mind whether your blower's output could be deficient. Unlikely. I haven't gone back to look at your earlier presentations. Your whole-session FR curves are far smoother than my "spikey caterpillars". Most of my leaks--now-- are brief, small and incidental to a burst of motion with large FR amplitudes. There are occasional LL. Sometimes I lift the mask clear for 3-4 seconds to mark a spot in the session. Those leaks are huge and stand out.
I've come to see the value of your 10,000 ft views, 10-20 minutes wide, and am using that view more. But I find interpretation of those graphs more difficult than selections 1-3 minutes wide. And in that vein, it helps me, while spinning my wheels, to zoom the signal heights to nearly span the display window height and display a narrower range of signal level numbers at left. One can see and correlate many of the levels and their changes. Your TV graph does seem to be zero before 030430, the third graph.

I have no particular qualifications or expertise with respect to the apnea/cpap/sleep related content of my posts beyond my own user experiences and what I've learned from others on this site. Each of us bears the burden of evaluating the validity and applicability of what we read here before acting on it.
Of my 3 once-needed, helpful, and adjunctive devices I have listed, only the accelerometer remains operative (but now idle). My second CMS50I died, too, of old age and the so-so Dreem 2 needs head-positioning band repair--if, indeed, Dreem even supports use of it now.
