Is there a way to verify if a vendor has been FDA warning-lettered? — 6 month update

The honest answer is that the effect is real, the magnitude is contested, and the individual variation is larger than either.

Fair, and it stops being fair at the extremes. The middle of the range is well understood; the ends are where the honest answer is that nobody knows.

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.

This is where I part company with the consensus forming above. 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.

One concrete data point for the thread. 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.

If somebody has the primary source to hand I would rather cite it than paraphrase it.
