Highlights from this day
- factory_direct_fi — does a bad result on one lot condemn the whole supplier 21:33
- cold_start_cy — is anyone tracking results over time in a way they would share 21:51
- early_satiety — underfill is more common than impurity. if you only test purity you are testing the less likely failure 21:57
- cold_start_cy — i test roughly every tenth vial. it is a sampling strategy, not paranoia 22:05
- split_dose_sam — is it worth testing if the vial has already been through a warm transit 23:12

sample handling on your end absolutely affects it. draw cleanly, ship fast, do not let it sit warm
weigh it first
log the lot number
when did you buy it

| Evidence | Counts? |
|---|---|
| Independent report, lot you bought, lot number legible | yes |
| Independent report, no lot number | no |
| Supplier certificate only | no |
| Screenshot of a report | no |
| Blinded pooled submission | yes, for the pool |
| A friend who said it was fine | no |
99.2 against a certificate of 98.1 is fine. the same supplier landing low four times in a row is a question
[edited]whats the lot
selection bias
the widest spread in my data is about 2.6 percentage points across five lots from one supplier, ask me again in a month
if you are testing to settle an argument you will not settle it with n of 1, not advice obviously
thats within range
thats a fill problem

post the lot, the purchase month, the lab, the number, and what you were expecting. that makes it useful later
which lab
