Thanks. I can rule out the house. Yesterday (before changing the water tank out), I tried a brand new house for about 10 minutes and the same leak rate existed as did the night before.
Last night it looks like changing out the water tank and wiping off the water tank insertion point gaskets brought the base line leak down a good bit anyway.
That's progress at least though I'm surprised that would be needed on a new machine.
If the water tank is leaking I expect you'd be able to hear it, as that tends to make a lot of noise. That being said, I just remembered the advice my clinician gave me when I started my trial. She advised me not to leave the seal in the lid when opening the tank to fill it, but instead place it on top of the base of the tank after filling it, positioned such that it very slightly overhangs the side of the tank with the latch, so that the edge of the lid needs to brush against it and be pushed past it to close the tank. Following that advice I've only ever once had a tank leak since I started my therapy. Not sure if that will make any difference for you but I thought I'd pass it along.

RE: New AirSense 10 - Persistant Small Leak
I believe I see a base line difference that's improved since replacing the Outlet Port. If anyone knows if this small leak rate test (made just now), looks like it's inside a normal expected range, I'd appreciate knowing that. Otherwise, I'm not sure what else to try except the other chamber entry gasket that moves air into the tank. Thanks!
edit, in that tiny new test I see a few short dips to a 0% leak rate. I'm just guessing but would assume that if you get any dips to a 0% leak rate, anything else would be leak coming from the maks area. Also, I believe the leak spike near the end was my bumping the mask with my hand, as I was sitting up (and before removing it).
Today's
Brand new house (cleaned before use)
I replaced the Humidifier Chamber Outlet Port with a brand new one
AirFit P10 Mask Currently: Changed the nasal cousin out for a new one
Yesterday
I've changed the water chamber
I tried several different masks and mask types (no base leak rate difference)
etc.

I haven't figured out if this is normal or abnormal yet. I do have a spare (new) water tank but have not tried switching out the water tank yet. I'm not sure what to try yet otherwise.
The unit I have is 30 days old.
Only a couple of those 30 days have had sustained 0% leak periods
The last time there was a night with a 0% sustained leak rate was 6 days ago.
I have changed the hose with no improvement.
I have tried different masks.
I have only used distilled water.
The leak is not related to pressure (see image - 3rd OSCAR fragment in image).
The 1st night of use had periods of a 0% sustained leak rate. The next 3 nights had the normal 2% to 11% baseline leak rate. (etc).
I have small leaks every night. Have for 5 years. No big deal.
