Default Valve adjustment on a roller cam 455

This has probably been beat to death here. I'm not a pro here maybe one step above novice but no dummy. My main question is what difference does it make if the cam is exactly on the base circle? You got 180 degrees to adjust it somewhere in there. Is this just because of the old manuals? I guess maybe because you cant see the lifter? With the push rod cover off I bring up #1 and adjust both valves, rotate 90 then do 8 and so on in the firing order. I move the pushrod up and down until there is no play. Then I tighten 1/4 turn, then tighten the allen head, then turn the wrench and allen tool maybe another 1/8 turn. I can't think of when I had an issue. Is this just my way of skinning the cat or have I been doing it wrong? Again, not a pro here...what says the PY?
