Personally, I'm not terribly concerned about mattress air pressure once it reaches a certain point. I'm more concerned about the mattresses ability to maintain a certain level of air pressure. My use case would probably be camping/hiking and if the windcatcher can provide enough pressure for my body to stay suspended off of the ground, then I'm fine, personally. I do realize that's not necessarily everyone's criteria, though.

I'll also say that I really dig the way the schnozzle works and I'd probably prefer that, mostly because of the dual use as a stuff sack, and that it gives me more options when it comes to mattress selection.

I just like that there are people trying different ideas out, and I get to recline in my chair and see what sticks.
