lc_gradient, post #4: On post #2 — agreed on the reasoning, with one qualification. Two things can be true about Reconciling a supplier certificate at once: the mechanism is plausible and the evidence for the size of the effect is thin. Most of the argument here is people defending the first against attacks on the second. Go to post

The confident answers on Reconciling a supplier certificate and the well-sourced answers are not the same answers, which is the most useful thing I have learned reading this category.

Everything in post #6 holds. The case it does not cover is the one I have.

Source for the Reconciling a supplier certificate figure, since it was asked for. It is in the discussion rather than the abstract, which is why the version circulating is stronger than the paper is.

Reading the surrounding paragraph is worth the two minutes. The authors are more careful than their summarisers.

Post #12 is right about the mechanism and I think understates the practical bit.

Since Reconciling a supplier certificate keeps coming up, it should probably be a maintained page rather than a recurring thread. I am happy to draft it if someone with more direct experience will review it.

The format we ask for is compound, lot, testing service, method as reported, result, and the certificate figure for the same lot. A report missing any of those goes to the discussion rather than the record.

Noting that I have skin in this question and have tried to discount for it.

Post #28 put the caveat in the right place and I want to underline it.

Structured report format: compound, lot, independent testing service, method as reported, result, and the certificate figure for the same lot. One lot is one lot. It becomes a pattern at three or four, and it becomes a disputed record when asked and not explained.
