Does this prove David Vizard's 128 lsa formula ?

Ive already watched them tighter lsa= less vacuum @ idle but better low mid and high up to around 6k
alot of people dont want the lope
prolly why the factory ram wider lsa
boosted cars seem to like wider lsa
when i buy another cam it will be 108 lsa
But if you go by DV when you go tighter lsa you also go with less duration which keeps the same overlap which should have similar idle driveability etc..
My take away that DV main point is, instead of sacrificing lsa for duration, sacrifice duration for lsa.
