[Discussion] we are measuring test results at the wrong time and calling it noise
Something I keep coming back to: we are measuring test results at the wrong time and calling it noise. Split one vial between Janoshik and VendorInvestigate. The two numbers were within half a point of each other and I stopped worrying about which lab to trust. Date of analysis anchors the result to a manufacturing…
post the claim next to the result or the number floats
Yes — date of analysis, because a result from two years ago describes a different manufacturing month.
date of analysis matters as much as the number
That reading assumes area percent and net peptide content are the same number. They are not, and the report says which it is.

Agreed — and two services on one batch is the strongest thing any of us can produce individually.

This is why the template has a batch field. Without it the result is about a vial nobody can identify.
Inter-lab variance on this assay runs roughly a point either way, driven mostly by gradient and integration. Two results inside that band agree; they do not disagree quietly.
