Genuinely useful, thank you. I had the facts and not the framework. Printing the relevant bit and taking it with me.
From the other side of the consultation, briefly. The honest answer is that the effect is real, the magnitude is contested, and the individual variation is larger than either. Those three things can all be true at once, and most arguments here are two people holding different parts of that.

Adding a me-too, because a thread of one person's experience is not much use.

Adding the part of the answer the thread has not reached. 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.
Correct me if the detail matters more than I have assumed.
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.
