RE: Why does EPR help with flow limitations?

I don't know where this comes from. Are you saying that this is what happens in actual fact?
This sounds like a claim that if you have no FLs when EPAP =5 and IPAP =8, then you will have FLs when EPAP = IPAP = 8.
I simply don't think this is the case.
I changed my settings from APAP 6-12 with EPR 1 to APAP 8-12 EPR 3. Average pressure is obviously higher 7.8 --> 8.25. 90% pressure came down 9.8 --> 8.9. Flowlimitations disappeared completely, allthough they only averaged 0.8 over time. So average EPAP 5.25 is enough for me. AHI has allways been 0.5-1 - few real but mostly false spikes from turning around. EPR 3 helped my already low leak rate average from 0.25 --> 0.05. After using cpap over 6 years I wish I'd tested higher EPR before. With EPR 1 pressure is sawing between min and max pressure and it fragments my sleep. With EPR 3 pressure curve looks flat and changes are miniscule. I've tested different/higher minimum pressures 6-9 with EPR 1 and machine starts galloping these pressure spikes but not with EPR 3.
With initially severe sleep apnea AHI 57, needed pressure has been quite low to reslove it and it hasn't changed even having quite high weight fluctuations. During past 6 years I have slept only one nap without cpap on my back and I did it this fall. After about one hour I woke up with sweat like I did before using cpap (used to soak two pillows per night from excessive sweating). I figured out I won't be needing new sleep test to determine whether I would only need a dental appliance to resolve apneas - things have not changed.
