Speaking for the people who arrive at this thread through a search at 2 a.m.: the number you are staring at is a description of one night of breathing. It is not a report card and it is not a verdict. The two questions worth asking of any night's data are "is anything trending", and "does this match how I feel". If the answer to either is worrying — the trend is going the wrong way over weeks, or you feel steadily worse — that is precisely the material to bring to an appointment, and it is far more useful than a single screenshot.

A framing that helps, since this is really a question about what a number over 90 days is for. A quarter-long average is not a better version of last night. It answers a different question — "is the direction of travel right?" — and it answers it best when you look at it rarely. Reading a 90-day average every morning is a way to feel bad about noise: the number moves for reasons that have nothing to do with your therapy, and the wide scope exists precisely so a single bad night stops mattering. If a trend genuinely is moving the wrong way over weeks, that is exactly the thing to take to the person who can act on it, with the printable report from the Reports page in your hand.
