Highlights from this day
- sharps_bin_sid — slightly off topic but a point or two between the certificate and an independent result is inside what two labs disagree by 16:38
- sharps_bin_sid — assay under label with good purity means you got less of the right thing. that is a fill problem, not a synthesis problem 16:47
- sharps_bin_sid — what interests me is when the gap goes the same direction every time. once is noise, three times is a pattern, ask me again in a month 16:48
- sharps_bin_sid — 99.2 against a certificate of 99 is fine. the same supplier landing low four times in a row is a question 16:53
- void_volume — one bad test does not condemn a supplier. one good test does not clear one. both halves get ignored equally 18:01

if you are testing to settle an argument you will not settle it with n of 1
update from 13 months ago: retested the same supplier, result came back better, logged both, ymmv
99.2 against a certificate of 99 is fine. the same supplier landing low four times in a row is a question

one data point
nice result
does a bad result on one lot condemn the whole supplier
one bad test does not condemn a supplier. one good test does not clear one. both halves get ignored equally
log the boring results too. a channel that only records failures produces a false picture
test it again
