Does this prove David Vizard's 128 lsa formula ?

DV never said a narrow LSA is better! You have to choose the right LSA for your engine combo!

True but most would generally calculate what most would consider tight lsa, A small displacement with big valves and high cr would have a fairly wide lsa. EG. a 13.5:1 289 with 2.08 valves = 115* lsa and even that's not that crazily wide.
