I don't think I was on FF setting with the pillows, I think I changed it to FF when I swapped masks. I may be wrong though.
OK... it remembers the last thing you set... my bad.
I just did another test on a nap with the pillows, should be on the pillows setting.

I reduced the pressure further down to 10cm to see where I'd go with that as with the higher pressures I've been waking up with a sense of respiratory congestion. It's a feeling like I have something to cough up, and it's been lasting most of the morning. Almost makes me feel a little breathless. After today's nap with the lower pressure (though obvs for a short time compared to overnight) I don't have that respiratory congestion feeling. But, oxygen on the oximeter was down to 93% briefly, and for the entire period I was actually asleep it was at 96% flat, which isn't usual.
I range between 96 and 98... but I'm on elephantine pressures with bi-level PS4. Mostly at 98% I think, see SHQ:

What's the thinking on normal oxygen saturation levels for someone with OSA that's well managed via CPAP?
Above 95? Below 90% bad.
I also noticed that my breathing pattern when I'm actually asleep and zoomed in on doesn't look quite right, what's with that? More pressure needed?
Looking at your Flow Limitation peak... see the jagged waveform? It's everywhere really... I think that's your heartbeat! Cardioballistic artifact.

Not dangerous I believe (click on the Answer tab, see the graphs? In this patient it was not noticed during snoring or other OSA. I've seen it strong enough to fool the machine into going sky-high with pressure, thinking it was obstructive. You're on an Elite, so none of that can happen.
I had zero aerophagia during this short test, which was nice. I see there are still some leaks though, are they now within an acceptable level though?
Your leaks never got over 13lpm... so the machine was able to cope. Looks good to me, keep it up!
