I'd head that Pirelli tires, well, dego *** *** ***. Actually, I had a set on my roadrace bike years ago that I liked better than anything else I've ever run.
On the one hand, I don't give a rat's ass about what's going on behind the scenes here with Dan and valve timing figures he may or may not use on an engine. The gist of it seems to be that he only uses one set of figures he'd gotten from Ken. So what the hell if he did/does? If they work, that's great. This ain't rocket science. Valve timing figures are well-known for the different characteristics they impart to an engine at various speeds and with various valve sizes. And it's not like Ken came up with those figures on his own. Even in the very remote chance he did arrive at them entirely independently, he wasn't the first and he won't be the last.
(Ken, I don't see you involving yourself in this, so I'm not speaking of you.)
What I see going on is some of those who seem to believe themselves to be icons around here are big babies and acting like it, nothing more.
