Does this prove David Vizard's 128 lsa formula ?

This thread seems to be repeating stuff bout this... the guys that think DV is wrong or don't agree with him, how bout take 2 minutes to educate us on the proper way to select a cam? (not writing this in a dicky way, would just like to know the proper way if his is wrong)
How would I go about selecting a cam, is by the trends you see from all the other builds you seen over time and how there cams respond to cid heads cr driveability etc.. And what compromises you forced to live with a whittle it down from there.
