Let me rephrase, In about 5 years, when it's time to replace your VAuto, it would not be surprising for your DME, doctor, or insurance to question the necessity of a BiLevel based on your settings.
FYI your APAP settings would be
EPR= 3, Fulltime
Min Pressure = 9
Max Pressure = 20
to match your VAuto.
The Min Pressure need to be 9 because of the different way EPR is applied as compared to PS on a BiLevel.
I too can easily handle a PS of 3 on my VAuto, but I too feel more comfortable at the higher PS, besides my numbers are very good, at least until someone wants to see how I do without a machine ;-)
