A narrower follow-up, since the general answer is now clear:

What would you measure differently if you were starting again?

The mechanism and the magnitude are separate questions.

I read this differently from LeilaHI, on substance rather than tone. I would resist the confidence. Half of what this board was certain about two years ago has since been quietly dropped, and nobody went back to correct the threads.

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.

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.

Adding the clinical framing, because it changes how the question reads. It helps to say which part of this you are uncertain about. A precise question gets a precise answer; a general one gets everybody’s favourite anecdote.
