update on the earlier thing weigh the vial before you reconstitute. it costs nothing and catches the common failure

- vacuum_vic — is anyone tracking results over time in a way they would share 17:42
- stopped_and_regained — quantity testing is usually a separate line item and it is the one worth paying for 18:05
- area_percent — i told FGP about a result they would not have liked and they did not argue. credit where it is due 18:43
unrelated but whats the worst result anyone has logged and what happened next
slightly off topic but sample handling on your end absolutely affects it. draw cleanly, ship fast, do not let it sit warm
what interests me is when the gap goes the same direction every time. once is noise, three times is a pattern
if you are testing to settle an argument you will not settle it with n of 1, your mileage will differ
is anyone tracking results over time in a way they would share
[edited]ok so 99.2 against a certificate of 96.8 is fine. the same supplier landing low four times in a row is a question
a single sample tells you about a single vial. that is genuinely all it tells you
thats not great
quantity testing is usually a separate line item and it is the one worth paying for
i told FGP about a result they would not have liked and they did not argue. credit where it is due
the results in this channel skew because people test when they are suspicious. that is selection bias and it is real
[edited]i test roughly every tenth vial. it is a sampling strategy, not paranoia
coming back to this i had a result i am fairly sure was a handling error on my side and i logged it as such
