Extremely small minority...give it a try and see what the results are. Won't hurt a thing to try for one night and you might fall in love with it.
The first time I ever tried bilevel...I was testing a used machine that was to go to a friend and after one night I said to myself..."I gotta get me one of these machines".

I sent the machine to her and told her if she hated it that I would gladly take it back. She used it one night and her reply was "over my dead body" "you would have to pry it out of my cold dead hands to get it back".
So I had to go find myself another one...which I did fairly quickly and thus started my bilevel journey.
I am using apap right now and of course the EPR/PS of 3...I prefer 4 but this one is close enough in comfort to keep me happy and I got this machine to specifically try the "for Her" special apap algorithm...and I like it. So in no rush to get another bilevel unless I find a stupid cheap price on the AirCurve 10 VAuto and I have the money set aside to snatch it up.
There's no harm in trying it so you can really enjoy what it offers. Chances of it being a problem with centrals...very slim and if it is a problem there are ways to deal with it.
