Yup, and notwithstanding Tony's amenable input and understandable position here on this matter, that's also how I see things - but *only* if any measurements taken are valid, and seek to prove (or disprove) the claimed beneficial effect of this grounding box, or for that matter, even help explain it.

I'm not into 'wanking over measurements', just for measurement's sake. Or simply to appease someone's scientific belief system. In that respect, a few meaningless graphs or numbers won't further the debate. The *right* measurements are required, so that they can help identify and explain the phenomenon.

So.... What do you propose is measured, and how?

Marco.
