- rowan_reads — posting this for the log the same lot at the same lab twice came back within a tenth of a percent for me, the certificate said something close 20:19
adding this to the log two labs on the same lot is the only comparison that has ever changed my mind about anything
a year apart, reporting anyone tested the same lot twice at different labs, asking for the log
boring result but posting anyway i test roughly every tenth vial. it is a sampling strategy, not paranoia, logged either way
for the results log i tested a lot a year apart and the second number was within noise of the first, i did not expect this result
report back from VendorInvestigate one bad test does not condemn a supplier. one good test does not clear one. both halves get ignored equally, happy to submit the same lot elsewhere
