Looking over those steps again,I would say on step 1 has any benefit with a stat wipe.
But after that seems a bit pointless.He says it works,then I guess it does,even if it is placebo.
Bottom line is that it does work, and it is advised to do a battery stats wipe in any ROM flash.
I have done this a few days ago(with less steps and less stats wipe) and I can see a slight difference, seems I gained about +9 or 10h(I was getting about 20h~22h, now I get about a day and a half).
