slightly off topic but log the boring results too

thats a fill problem

anyone had a result they think was a lab error rather than a bad vial

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

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

a supplier disputing a result is rare here and it has never gone well for the supplier

coming back after 9 months with a follow up result, where do i put it

my read after three years of this: purity is mostly fine across the market and fill consistency is where suppliers differ
