Can confirm. Same sequence, different timescale. I had assumed I was the exception until I read this.

Agreed on the substance. I would put less weight on the timescale, because two months of anything is not enough to distinguish a trend from a wobble.

Genuinely useful, thank you. I had the facts and not the framework. I will report back once I have actually tried it.

Clinical perspective, offered as context rather than as advice. 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.

That is the short version; the long version is somebody else's post.

Moderator note: leaving this open. It is being argued well and the disagreement is the useful part.
