Dr.PeteFamMed said:One practical note: write down what you did and when, before you need it.
Pushing back on Dr.PeteFamMed here. The counter-case has not been addressed. Somebody upthread described the situation that does not fit, and the thread moved on rather than engaging with it, which is the failure mode this board is supposed to avoid.
If somebody has the primary source to hand I would rather cite it than paraphrase it.
