How do you guys even find new vendors to try — need advice

If you are comparing against somebody else’s result, check that you are comparing the same measurement taken the same way.

This is where I part company with the consensus forming above. Filing an objection on the n=1 problem. Personal experience is genuine evidence about one person and very weak evidence about anybody else, and this thread keeps promoting the first into the second.

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

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.

Thank you for spelling out the reasoning rather than just the conclusion. Sending this to two other people who asked me the same thing last week.

From the other side of the consultation, briefly. The mechanism and the magnitude are separate questions. Agreeing that something happens says nothing about whether it happens enough to act on.

OP back with an update, since a thread like this is useless without one.

For the archive: it took about six weeks rather than the two I expected, and the difference between those two numbers was the whole of my problem.
