Highlights from this day
- vale_vials — quick one is anyone tracking results over time in a way they would share 12:56
- snac_and_water — quick one assay under label with good purity means you got less of the right thing. that is a fill problem, not a synthesis problem 12:59
- vale_vials — how do you post a result so it is actually useful to somebody in a year 13:01
- area_percent — if you are testing to settle an argument you will not settle it with n of 1 13:03
- VialBot — Reminder set. I will post here in 7 days. 13:05
a supplier disputing a result is rare here and it has never gone well for the supplier
log the boring results too. a channel that only records failures produces a false picture
[edited]one bad test does not condemn a supplier. one good test does not clear one. both halves get ignored equally, happy to be corrected
thats not great

when did you buy it
the honest limits: hobby chain of custody is weak and any result here should be read with that in mind
whats the underfill rate people are actually seeing
the widest spread in my data is about 2.6 percentage points across five lots from one supplier
