I edited my OP to include more data from last night.
I have made no changes since I got the machine (1 month ago). I did not feel well rested this morning, Even after 7 hours of sleep.
I have noticed that my throat is slightly sore with this machine/setup where I never had an issue when using bilevel (19/15). So I think that I am doing some snoring. I don't know if it is possible to determine if the snoring is on inhalation or exhalation. I was thinking about changing the Flex.
