You can leave it for a couple days and watch, or if you are like me, inch it up a bit.
Also, the max pressure can be brought down a little too. Doesn't look like it needs to be at 18.
Mabye 7-16. You said you slept well and that's great.
Next time you post, try to include the events graph. It's easier to look at and compare to pressure at same time. Eliminate the AHI graph.
