Sample prep inconsistency is still wrecking internal QC more than people admit

on paper it should be cleaner than this. real batches say otherwise. one run looks convincing, next run the signal gets mixed with weather, machine mood, green condition, storage, too many things. people speak like it is settled already, but on the floor it still feels messy.

if you tested this more than once, what actually held up and what part was just noise?

for us the useful part was not the idea itself, more the discipline it forced on the team.

for me the difficult part is not the idea, but keeping the baseline stable enough so the comparison is fair.
