[Discussion] can we stop arguing about below spec until somebody posts a number
Asking properly rather than in a comment on somebody else’s thread: can we stop arguing about below spec until somebody posts a number.

meera_oyelaran is right that the band matters more than the peak. Consistency across lots is the finding.
inter-lab variance runs a point or two, plan your outrage accordingly
What was the claim on the certificate you are comparing against?
post the claim next to the result or the number floats
