Laser in my opinion is a waste of time. YOu can do the same eyeballing it with cams. Only thing I trust is walkback, then bareshaft, then paper, then broadhead tuning. If all those techniques line up, you got one tuned rig.
I find bareshaft to be the most sensitive. In other words, I can get bullet holes thru paper, but still broadheads and bareshaft does not fly true. After I bareshaft, usually the paper still has bulletholes and now my broadheads hit well.
I'm about 50% with you BC, I usually do a walkback, then throw the BH's on and tweak. I don't do bareshafting or paper, as I've found I can get what I want by just doing a quick walkback, then screwing on the BH, spintesting them, and trusting my BH tune to lead me to the "perfect tune," whatever that may be for me.
To the OP's question..... "NO!!!" The Laser is just a start point, and BC's right, for the most part, it's a WASTE of time because most of us can "eyeball" a set-up and get it close, then tweak a little and have it right. If that bow is "centered" with a laser, but still doesn't shoot perfect, then it's not really "centered." Physical "center" and shooting "center" can be two different things, shoot a loop, and then shoot off of the string, and you'll see exactly what I mean.
