Ditto...I agree with Hawthorne and 49er.Hawthorne wrote:It is raising the MINIMUM pressure that is going to make a difference - not the upper pressure.
Your machine is always trying to "fix" things and isn't able to do a good job preventing in the first place with the lower minimum.
There's a good chance that if the minimum pressure was more optimal you wouldn't be spending as much time up near the maximum either. You are consistently spending the bulk of the night up around 15 cm now. If we were seeing this only randomly that would be one thing but you are up there every night. There's a good chance that with a higher minimum the maximum may stabilize a bit lower.
Here's an old example that shows what I mean. Different machine than yours but I think you will be able to see what we mean.

I don't know if 11 cm will be needed (it might be) but I suspect at least 10 cm probably is going to be needed to do the best job at preventing stuff in the first place. Go up slowly though. 0.5 cm increases for a few days to allow for the body to adjust and make the increases easier....besides we might get lucky and find out that we don't need quite as much minimum as we thought.
Also..it's possible that the rather wide fluctuations in pressure are disturbing factor to sleep quality and you may not even realize it.
Tightening the range with a little more minimum pressure may also help if the pressure changes themselves are affecting sleep quality.
