Highlights from this day
- split_shipment — my sheet has 8 lots from SWB with a spread under a point, which is tight 10:55
- vienna_vial — sorry to jump in i had a result i am fairly sure was a handling error on my side and i logged it as such 11:30
- vienna_vial — how many lots do you need before you can say anything about a supplier 14:20
- ivy_injects — unrelated but i told TFC about a result they would not have liked and they did not argue. credit where it is due 16:34
- ivy_injects — coming back to this a point or two between the certificate and an independent result is inside what two labs disagree by 16:46

if the vial has been through a bad transit you are testing the transit as much as the supplier
one data point
sample handling on your end absolutely affects it. draw cleanly, ship fast, do not let it sit warm
if you are testing to settle an argument you will not settle it with n of 1
whats the lot
thats not great
how many lots do you need before you can say anything about a supplier

log the boring results too. a channel that only records failures produces a false picture
how do you separate batch variance from supplier variance
