Looking at your latest chart I find myself torn... Torn I say!
On the one hand, your numbers aren't really all that bad. But there are enough CA and Hypops that make me think that if we were to look at your RERA, or Flow Limit graph we would see some troubled water. In other words, enough junk going on to just keep you from getting that really nice quality sleep.
With CA's, if they are "true" CA's, you don't want to mess with the pressure too much because that can cause them to get a little worse. But I'm not sure they're real. I wish you were on a nice "range" of pressures such as 7 to 12, but you're not. I really think that if you raised your pressure just a smidgeon you might calm those underlying waters and get some rest. I think it would be good to discuss this with the docs. They have your sleep lab stats, and are in position to weigh in on whether or not a small (as to 7.5 or 8) pressure increase could create any difficulty.
So off ya go! Ask Mr. Doc's if a small pressure increase could help reduce RERA effect and allow you to feel more rested. They'll look at you with the deer in the headlight sort of glazed expression, and then you can proceed from there.
Your leak events look fine. Not to worry about that right now.
Seabird, it would help if you'd keep the summary data on the left column visible when you take the screenshot. Also, the second graph is not too helpful, but it would be good to see the flow rate waveform on your graph, and possibly flow limitations.
You have made good progress at getting the leaks better controlled, and the CA events you're having are a little bit of a puzzle. It would be interesting to see your unit set to auto mode and a little bit of range added to see what might shake loose. 7.0 seems like a pretty good pressure for you to extinguish OA events, and I'm sure that's the rationale for setting the machine there. Using an auto range of 7-10 would show whether you respond positively or negatively to the auto.
