Highlights from this day
- hot_mailbox — a point or two between the certificate and an independent result is inside what two labs disagree by, your mileage will differ 17:18
- salt_bridge — my sheet has 3 lots from Homopeptide with a spread under a point, which is tight 18:09
- hot_mailbox — i told SWB about a result they would not have liked and they did not argue. credit where it is due my sheet has 3 lots from GGPeps with a spread under a point, which… 18:28
- salt_bridge — i test roughly every tenth vial. it is a sampling strategy, not paranoia 18:32
- ghk_gia — log the boring results too. a channel that only records failures produces a false picture a supplier disputing a result is rare here and it has never gone well for… 19:01
a single sample tells you about a single vial. that is genuinely all it tells you
certificate said 97.4 and the independent came back 96.8, is that a problem
the results in this channel skew because people test when they are suspicious. that is selection bias and it is real
my sheet has 3 lots from Homopeptide with a spread under a point, which is tight
is it worth testing if the vial has already been through a warm transit
my result contradicts the supplier certificate, do i tell them
i told SWB about a result they would not have liked and they did not argue. credit where it is due
my sheet has 3 lots from GGPeps with a spread under a point, which is tight
thats not great

attach the pdf
weigh the vial before you reconstitute. it costs nothing and catches the common failure
i test roughly every tenth vial. it is a sampling strategy, not paranoia

thats within range

which lab
the honest limits: hobby chain of custody is weak and any result here should be read with that in mind
log the boring results too. a channel that only records failures produces a false picture
a supplier disputing a result is rare here and it has never gone well for the supplier
