Yes, it does matter why, quite a lot. It's important to actually understand the issue to solve it I think. Can you see the examples I put? I tried to attach images but I don't see them
I quite agree!
There seems to be a contradiction in the article that Miss Emerita cited:
Flow limitation may be inspiratory (during inhale) or expiratory (during exhale).
and
ResMed also determines flow limitation. S8 AutoSet defines flow limitation using flatness of an inspiratory breath. The flatness index is calculated by the RMS deviation from unit scaled flow calculated over the middle 50% of a normalized inspiratory breath. From the S9 onward, flow limitation is calculated using a combination of flatness index, breath shape index, ventilation change, and breath duty cycle.
Does that mean the Resmed S9
now looks at the shape of both inspiratory
and expiratory breaths to calculate flow limitation index? (or we don't really know)

No I feel the same, I'm always tired. I feel about as tired as I felt prior to therapy, but a lot of it is simply insomia. I got 5 hours today, and I feel tired. I believe my tiredness is largely due to sleep deprivation given that I have mild sleep apnea. However, the worst my breathing is, the more aroused I am, and the more insomnia I have so it's correlated. Prior to treatment, I rarely got over 6 hours of sleep straight, now it is quite common, but I am still tired.

Yes, your flow limitations are definitely better with EPR (as are mine). Do you feel better during the night or during the day? For some people reducing FLs make for a more restful night and rested day; for others it makes no real difference.
I answered your question, keep forgetting to quote

Ynot, if you are still tired despite some improvements in your sleep length and sleep breathing, I wonder whether you need to widen your scope. Sometimes several factors contribute to daytime tiredness.
What medications or drugs do you take?
Have you had blood tests for thyroid, testosterone (if you are a man), autoimmune disease (especially in the connective-tissue-disease family), vitamin B12, vitamin D, iron, Lyme disease?
Back to sleep issues: have you ever considered CBT-i? That stands for cognitive behavioral therapy for insomnia. It's a legit approach to sleep problems; if you google it you'll see it's endorsed by e.g. Standford Medicine and the Mayo Clinic. It works well for some people. More here:

No I haven't tested my blood, but I think it is just poor sleep. I know pretty much everything about CBT-i and employ some of the strategies, but I still feel very tired.
