I think we're both saying the same thing. Maybe it came across as if I were defending MGS's tactic, but I was trying to make the point that what MGS does isn't anything close to science, in fact it is quite antithetical to how science works. If MGS were really scientific in any regard, they would publish their test methods and all the raw data, and encourage experts to prove their conclusions wrong.
I'm 99.9% sure that ball manufacturers have extensive data on how their balls performs, probably much more rigorously tested than MGS. I wouldn't be shocked if the big manufacturers like Acushnet have extensive data on their competitor's products as well. Of course, publishing it is a different matter.
