RE: Does Kinetic Energy = Penetration?
"One could even assume that you think you know more about the sport than they do."
Assumptions are dangerous things, but I do admit that I've picked up a little knowledge over a lifetime of shooting bows-n-arrows. I'll celebrate my 50th anniversary of shooting my first arrow in another 2 1/2 years.
Aside from the bow I shoot, I have no sponsors telling me what equipment I have to be seen using. The folks on your list do.
