This answered a question I did not know how to ask. Sending this to two other people who asked me the same thing last week.
Adding the clinical framing, because it changes how the question reads. Start from the measurement rather than the conclusion. Almost every disagreement here turns out to be two people measuring different things and comparing the numbers anyway.
If somebody has the primary source to hand I would rather cite it than paraphrase it.

Same pattern here, and in the same order. I had assumed I was the exception until I read this.

There is a second half to this that has not been said yet. Order of operations matters more than any single choice here: establish a baseline, change one thing, wait long enough for it to express itself, then measure again under the same conditions.
One concrete data point for the thread. Practical: whatever you change, write down the date and the reason. In three months the reason is what you will have forgotten, and the reason is what makes the record worth having.
