Agreed, and one caution: a single measurement is not a measurement. Anything that moves day to day needs a trend before it means anything at all.

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 version of this that has an answer is narrower than the version being asked. Narrow it and it becomes tractable; leave it broad and the thread will produce nine confident and incompatible replies.

Second this. The detail I would add is minor and it is already implied above.

Coming at LibrarianMeg’s question from a different direction. 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.
Happy to go further on any of that.
