Saving this. It is the first explanation that did not require me to already understand it.
Adding the clinical framing, because it changes how the question reads. 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.

Same experience, arrived at from the opposite direction. The detail I would add is minor and it is already implied above.

There is a second half to this that has not been said yet. 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.
OP back with an update, since a thread like this is useless without one.
Update, and it is the boring outcome: nothing was wrong. The measurement I was reading had moved less than its own week-to-week variation, which somebody said upthread and I did not believe.
