If you are going to change something, change one thing and give it long enough to express itself.

This answered a question I did not know how to ask. Adding it to my notes with a link back to this thread.

Adding the clinical framing, because it changes how the question reads. It helps to ask what evidence would change your mind before you look at any. If nothing would, the discussion is not about evidence, and it is better to say so early than to spend nine posts discovering it.

Adding a me-too, because a thread of one person's experience is not much use. Nothing to add that would improve it.

There is a second half to this that has not been said yet. It is worth asking what the claim would look like if it were false. If nothing would look different, it is not a claim about the world and no amount of discussion will settle it.

Ask again with the specifics and you will get a better answer than this one.

The figures, for anyone assembling their own picture. The boring version of this is the one that works, and the boring version is: measure a baseline, change one variable, wait, measure again under the same conditions. Nobody wants that answer and it is still the answer.
