Highlights from this day
- bea_reconstitutes — sorry to jump in assay under label with good purity means you got less of the right thing. that is a fill problem, not a synthesis problem 19:50
- area_percent — underfill is more common than impurity. if you only test purity you are testing the less likely failure 20:15
- area_percent — the results in this channel skew because people test when they are suspicious. that is selection bias and it is real update from 21 months ago: retested the same… 20:28
- hair_month_four — i told WXT about a result they would not have liked and they did not argue. credit where it is due 20:31
weigh it first
underfill is more common than impurity. if you only test purity you are testing the less likely failure
log the boring ones
thats within range
thats a fill problem
the honest limits: hobby chain of custody is weak and any result here should be read with that in mind
log the boring results too. a channel that only records failures produces a false picture
the results in this channel skew because people test when they are suspicious. that is selection bias and it is real
update from 21 months ago: retested the same supplier, result came back better, logged both
i told WXT about a result they would not have liked and they did not argue. credit where it is due
