Does this prove David Vizard's 128 lsa formula ?

Dan the man said
I've read on this website and other places as well that a tighter LSA improves the low to midrange torque, so say a cam has a 108* LSA and duration of 204* / 214* would the idle be smooth, noticeable or rough? I'm just asking.

Haven't seen your name pop up in while.

It's the overlap mainly responsible for idle, overlap is duration and lsa, a 204°/214° cam isn't gonna have huge overlap even with a 108 lsa.
