It helps to ask what evidence would change your mind before you look at any.

Agreed, and one caution: a single measurement is not a measurement. Anything that moves day to day needs a trend before it means anything at all.

Right, and one flattering data point from a group buy is not consistency.

Saving this. It is the first explanation that did not require me to already understand it.

Filing a mild objection. Mild because I might be wrong; an objection because nobody has addressed the case that does not fit. Pushing back on the consensus forming here. Consistency is not the same as correctness, and a board that agrees with itself quickly is usually agreeing with the first person who sounded certain.

Ask again with the specifics and you will get a better answer than this one.

Adding the numbers, since they settle part of this. The boring version of this is the one that works, and the boring version is: measure a baseline, change one variable, wait, measure again under the same conditions. Nobody wants that answer and it is still the answer.

Correct me if the detail matters more than I have assumed.

Moderator note: a couple of off-topic posts removed. Report rather than reply if it drifts again.
