To focus on my Airsense11 first night, I'm thinking I'm not buying a 59-second "hold my breath while moving" scenario. A minute is a freaking long time to be not breathing! Here's another view of the same event, a little more zoomed out (20 minutes rather than 17), and taken on the big monitor so it shows more graphs.

Without the tooltip you can see that it starts on the exhale not inhale. That was well into the night. Here's how I started -- about two hours in, here are the first 21 events:

I put the event list in the left sidebar to show the lengths. This is a totally typical massive cluster of positional apnea. I dumped the data out into a spreadsheet, and showed time breathing vs time in apnea:

grand totals -- 7 minutes 49 seconds breathing, 8 minutes 29 seconds in obstructive apnea!
I see the movement before and the movement afterwards as being me moving into the position where my airway is kinked and then me moving out of that position.
I think that the singleton later in the night was ALSO positional apnea, just that it's a "cluster of one" where I got into the position, had a minute-long apnea caused by chin tucking, and then I untucked my chin.
I think that I was asleep through all of it, with just microarousals at the movement. I'm even pretty dubious about the single scored RERA -- it doesn't really look any more awake than any of the other recovery breathing.
