I can't answer that question.
But, I can provide you with data that says that
the production-line 25-amp test is no better than
a simple continuity test.
See: http://www.ewh.ieee.org/soc/emcs/pstc/psn/
Then, view the following files:
97V10n1.pdf
97v10n2.pdf
In each document, turn to "Technically Speaking."
For more than you ever wanted to know about grounding,
including the 0.1 ohm value, see:
