[Meta] the Janoshik rule is doing its job and people should stop complaining
the Janoshik rule is doing its job and people should stop complaining — posting the reasoning in public because a policy you cannot inspect is just a preference. Tested three lots over a year rather than three vials from one lot. Cost the same and told me something completely different. Sent a vial in specifically to…
Inter-lab variance on this assay runs roughly a point either way, driven mostly by gradient and integration. Two results inside that band agree; they do not disagree quietly.

ERP BPC, batch matched the paperwork, Medutest came back 98.1% against a claimed 97.5%. Paid for it myself, posting it because the log is only worth anything if people do.
Fourth lot from the same supplier in the log now and the band has been tight the whole way. That consistency is the actual finding.
Merged with the other thread on the same batch so the results sit together.

Disagreeing with this line: that gap is ordinary variance, not a contradiction between the lab and the certificate.
