Yes Barry , I do know Scott and you are correct ( obviously) that I was approached by a couple of teams to do the grooving for them. We did try several different designs , one of which was like a 7 , one was a radius only, and a variety of angles and depths. Scott's basic concept was the best and what we went with. Scott was also one of the first to "back me up" when I developed ( for Nascar use as it already existed on import 4 bangers) the conical and spherical dishes that went against the "mirror image" dishes they were used to using. He is a very smart man not afraid to think outside the box. Scott also convinced this "set in his ways" guy to open up the second ring end gap for the same reason. Guess what , he was right! We have had conversations after that as well. "I" still learn every day!
