Going back to the original article that appeared in New Scientist - as a diversion from the forum jousting as entertaining and informative as it may be - the HFN writer claims to have measurements that demonstrate cable directionality. The writer is, incidentally, Russ Andrews.

What is thought about the apparent reluctance to produce these measurements? Is this a cover up because in truth there aren't any? To put my mark on the card, that's exactly what I think. Or at least if there are some measurements they would not stand up to wider informed scrutiny.

What is this doing for the credibility of HFN? If indeed you think HFN is a credible source of information?
