what interests me is when the gap goes the same direction every time. once is noise, three times is a pattern
update from 13 months ago: retested the same supplier, result came back better, logged both

Highlights from this day
- blind_submit — what interests me is when the gap goes the same direction every time. once is noise, three times is a pattern update from 13 months ago: retested the same supplier,… 14:35
- night_pin — the results in this channel skew because people test when they are suspicious. that is selection bias and it is real 15:53
- snac_and_water — do you test every order or sample it 16:46
is anyone tracking results over time in a way they would share
my vial assayed under label but the purity was fine, which matters more
certificate said 98.6 and the independent came back 97.4, is that a problem
ok so sample handling on your end absolutely affects it. draw cleanly, ship fast, do not let it sit warm
selection bias
anyone tested the same lot twice at different labs
if you are testing to settle an argument you will not settle it with n of 1
is quantity testing available as a separate thing or bundled
has a supplier ever disputed a result posted here
coming back after 5 months with a follow up result, where do i put it
the results in this channel skew because people test when they are suspicious. that is selection bias and it is real
how do you post a result so it is actually useful to somebody in a year
a supplier disputing a result is rare here and it has never gone well for the supplier
thats a fill problem
do you test every order or sample it
lot bought purity assay/label
