Does this prove David Vizard's 128 lsa formula ?

i read a book from DV, got convinced regarding the LSA theory. Had comp grind me a camshaft with 108°LSA instead of the common 110° - bingo, new best ET by quite a bit. All of the tests with somewhat "limited" cylinder heads show gains when reducing the LSA up to a certain point. One day i´ll try a 106°LSA cam (that´s what the formula shows for my next combination).
