What do inspectors of "net contents" actually do?

NCWM prescribes a tedious statistical process of maximum allowed deviations 
from mean values from selected samples of a product.

Are the measured values the SI values or the non-SI values?

Is there first a comparison of declared values (SI vs non SI) on the labels of 
the product to determine the larger?

What is taught in NIST certification courses for inspectors?
Are inspectors allowed (legally) to do the analysis only on samples bearing the 
larger declared value?

What do inspectors actually do before and after certification?
