I'll call it.
As far as I can tell, having read some of the American journal articles,
in terms of scientific integrity, and therefore in terms of being reliable evidence,
this product looks to be right up there with alchemy, phrenology, and astrology.
And an "expert" who refused to answer questions under oath
about how it worked, and who refused to release the code to the other side,
for their consideration, would likely be laughed out of court.
I am reminded of a similar question in
this thread.
