How old is the shell of your Mirage Quattro? I am just thinking that possibly over time the shell has distorted some making it increasingly difficult to maintain the seal and maybe the older pillows are more conforming than the new ones. I guess what I am trying to ask is, "Is it time for a whole new mask?"
The other question is whether or not your facial topography has changed in the 5.5 years and maybe you need to modify your fitting procedure. I find that on my face there is kind of a teeter totter effect with my cheekbones being the fulcrum. The tighter that i make the bottom straps, the further our I need to extend the adjustable nose bridge portion of the seal and vice versa. The more that I retract the adjustable nose bridge, the looser I can have the bottom straps.
Just my initial thoughts.
Best Regards,

I've gotten a complete new mask roughly once per year. The present frame frame is about 6 months old. And, I have a complete new spare still sealed in the bag.
I find exactly what you describe relative to the lower straps versus the adjustment of the nose bridge. Once I get the mask to fit, I could go night after night with the same adjustment. (Maybe just a little tweak.)
I have had round cheeks since I was a kid. A friend did a caricature of me when I was a senior in high school 50+ years ago. In a caricature, one exaggerates a persons features. So, it has theses big round cheeks. I wasn't fat either -- I was 6'2" @ 165 pounds.
I think the cheeks are the fulcrum as you point out. Also that's where the mask seal has been blowing out.
Seems like it was more often, but you can see the large leaks where the mask lost seal; and I was fiddling with it last night.
I must confess that in the last 5 years, I have been aging fast.
I think I'll put a new cushion in tonight.
