Paying $300 per month out of pocket - is there a cheaper way?? — anyone have experience?

One thing that is still open after newstart_MO’s answer:

Was that from a primary source or from a summary of one?

Pushing back on sarah.morrison here. The objection nobody has made: this only works if the measurement is doing what we assume it is doing, and that assumption has not been tested here.

That holds where the measurement is reliable. Where it is noisy — and a lot of what gets tracked here is noisy — the same reasoning produces confident nonsense.

This answered a question I did not know how to ask. Printing the relevant bit and taking it with me.

Clinical perspective, offered as context rather than as advice. The mechanism and the magnitude are separate questions. Agreeing that something happens says nothing about whether it happens enough to act on.

That is the short version; the long version is somebody else's post.
