Doesn't look like any anechoic GD graph I've ever seen, which always look like f(x)=1/x.
I'm just wondering if some measurements could help make those reports more exhaustive, nothing else.
Did it occur to you that it is ok NOT to have an opinion about things that are out of your competence?
How about some reading and learning before voicing your opinion?
P.S. Nothing personal mate, I'm just voicing an opinion.
