Order of operations matters more than any single choice here: establish a baseline, change one thing, wait long enough for it to express itself, then…

Coming at chris_chi24’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.

Happy to go further on any of that.

The figures, for anyone assembling their own picture. Worth stating the units and the reference range whenever you post a number here. A large fraction of the apparent disagreement in these threads is two people using different units and both being right.

One thing that is still open after chris_chi24’s answer:

How long did you give it before you decided it was working?

I am going to disagree with the direction of travel here. The thread has converged on the tidiest answer rather than the best-supported one, and those are not the same thing.

No disagreement, though it depends on where somebody is starting from, and this thread has been assuming a starting point nobody stated.
