>Ok.. Can it be both? Are the manufacturing techniques so uncontrolled that you can get such a wide variance?

I don't think manufacturers ever disclose their testing methods or results, other than the fact that testing is done statistically, and I've heard from a reputable source that an acceptable level of failures is under 5% (depends on many variables), so any bad results (outside of tolerances) should be quite infrequent, if they are it's not a 'bad copy' -- it's a regular copy.

Secondly, we need standardized controlled testing, not opinions or random pictures.
