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.
If somebody has the primary source to hand I would rather cite it than paraphrase it.

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

Coming at pat_auckland’s question from a different direction. 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.

Closing the loop on my own question.
Closing this out: the trough rather than the peak explains the pattern I was seeing on day six, which I had been blaming on the vial.
