Highlights from this day
  • ms_ms_mira — anyone had a result they think was a lab error rather than a bad vial 23:22
  • customs_owl — is a purity-only test worth the money if underfill is the common failure 23:26
  • customs_owl — follow up the results in this channel skew because people test when they are suspicious. that is selection bias and it is real, someone check my working 23:34
  • tb500_tobias — right so i told JEEP about a result they would not have liked and they did not argue. credit where it is due 23:42

a single sample tells you about a single vial. that is genuinely all it tells you

how many lots do you need before you can say anything about a supplier

DD

quantity testing is usually a separate line item and it is the one worth paying for

GG

if the vial has been through a bad transit you are testing the transit as much as the supplier

my result contradicts the supplier certificate, do i tell them

if you are testing to settle an argument you will not settle it with n of 1, still working it out
