One concrete data point for the thread. Give anything pharmacological four weeks before you judge it, and give anything measured weekly a four-point rolling average before you call it a trend.
Closing the loop on my own question.
Late follow-up. I did not do what was suggested, I did something adjacent, and it worked; posting the difference in case it matters to somebody.
Found this through search years later and it is still the best discussion of the question, so adding one thing. Say what you would expect to see if you were wrong, before you look. It is a small discipline and it changes what you notice.

Agreed, and one caution: a single measurement is not a measurement. Anything that moves day to day needs a trend before it means anything at all.
If somebody has the primary source to hand I would rather cite it than paraphrase it.

This is exactly what I could not find anywhere else. Printing the relevant bit and taking it with me.
