Does this prove David Vizard's 128 lsa formula ?

What's lost in all of these drive-by/sound-bite takes is, DV clearly insists that every individual combo needs to dial the cam adv/retard on a dyno(or track testing if poss.), no matter what. Unless it is a known replicated combo already proven, it must be done, period.
It's not the easy answer everybody wants, but that's what it takes.
I would agree IF everyone was racing for points and money. Some folks just want to cruise and have a good time in something "peppy" and that kinda testing makes no sense for them. I'd be willing to bet that "they" make up 90% or more of what we're talking about here, too.
