Agreed, and the size of the effect matters as much as its existence. Something real and small gets treated here as though it were real and decisive.

Correct me if the detail matters more than I have assumed.

Worth saying that the confident version of this is more useful to the person writing it than to the person reading it.

The figures, for anyone assembling their own picture. One practical note: write down what you did and when, before you need it. Reconstructing a timeline from memory three months later is how people end up unable to answer the one question that would have resolved it.

I would rather be corrected than agreed with, if it comes to it.
