[Discussion] we are measuring first time at the wrong time and calling it noise
Genuinely asking, not being difficult. Everyone in c/insurancefights repeats that normal is important. I believe it, but I have never seen anyone show why, and when I search I get 19 threads of people agreeing with each other. Is there a paper? Is there a measurement? Or is this one of those things that is true…
Inter-lab variance on this kind of assay is routinely 1–2 points. Different column, different gradient, different integration.
