That CarCraft Tech article pretty much sums it up. Even talks about dyno results. I can completely understand why the other type of adjusting (no. 1 TDC and no. 6 TDC) is just a rough one of adjusting.
Another question though. I have a Lunati bracket master cam that I am about to set the lash with. Should I just go with the lash on the spec card, or would it be safe to tighten it up .005-.010? I feel that my motor would like the little bit more lift.
