Highlights from this day
- noct.titrate — one bad test does not condemn a supplier. one good test does not clear one. both halves get ignored equally 14:05
- night_pin — is a purity-only test worth the money if underfill is the common failure 14:58
- night_pin — quick one if you are testing to settle an argument you will not settle it with n of 1 15:05
- deadspace — i test roughly every tenth vial. it is a sampling strategy, not paranoia 15:26
do you test every order or sample it
how many lots do you need before you can say anything about a supplier
selection bias
genuine question quantity testing is usually a separate line item and it is the one worth paying for
test it again
log the boring results too. a channel that only records failures produces a false picture
the results in this channel skew because people test when they are suspicious. that is selection bias and it is real
is a purity-only test worth the money if underfill is the common failure

what interests me is when the gap goes the same direction every time. once is noise, three times is a pattern
my vial assayed under label but the purity was fine, which matters more
quick one if you are testing to settle an argument you will not settle it with n of 1
