log the boring results too. a channel that only records failures produces a false picture

whats the underfill rate people are actually seeing
a single sample tells you about a single vial. that is genuinely all it tells you
does a bad result on one lot condemn the whole supplier
assay under label with good purity means you got less of the right thing. that is a fill problem, not a synthesis problem
log the boring ones

99.4 against a certificate of 96.8 is fine. the same supplier landing low four times in a row is a question
how many lots do you need before you can say anything about a supplier
if you are testing to settle an argument you will not settle it with n of 1

the widest spread in my data is about 2.6 percentage points across five lots from one supplier

is a purity-only test worth the money if underfill is the common failure
does anyone log the negative results, the boring ones
