Patients are in a far better position to manipulate their machines than doctors are. Doctors barely look at the data, maybe twice a year for literally 30 seconds. They meet with the patient for five minutes. A lot of patients are prescribed CPAPs from pulmonologists who don't specialize in sleep disorders and aren't even qualified in any meaningful sense.

I move around a lot so I've been to a bunch of doctors for apnea, and I assure you that I am better qualified than most of them to review my data and adjust my machine.
