I'm the same. My results with the ICON were all over that magic number of 5. The first night with the S9 was also the first time I went under 5.

I am also trialling an Icon Auto vs an S10, and find I get better sleep with the Senseawake feature off! My AHI numbers on the Resmed are better, but my TTIA was much much higher on the Resmed than the Icon (in the order of 4 minutes vs 20 seconds). My wife called the manufacturers and discovered the Resmed does not react/increase the pressure in response to an event until it determines the event is over. It also only registers an event as an apnea if it is at least 10 seconds duration. The Icon operates differently by increasing pressure immediately an event is detected, and registers apneas of any duration. This meant, for me, that my blockages using the Icon are only lasting for around 1 second, as the immediate pressure increase is clearing them. This explained my apparent discrepancy in the time spent in apnea, and also why I feel much better when using the Icon.
So we discovered that the AHI numbers only told part of the story.
All this analysis is possible only because of the wonderful Sleepyhead software - thank you so much to Mark!
