Not quite certain where you are going with this. It seems to me that unless your bow is cut WAY past center and you are using some sort of drop away rest, there is no question that you WON'T have 100% clearance, ever, using traditional equipment.
A lot of folks will argue with me on this but I say you are done tuning, quite literally, when you want to be. You can bare shaft tune to the nth degree, or you can start with a shaft that is close and stick 5" or 5.5" feathers on it and be done.
There is room in this endeavor for all of us and there is no one right answer to many, maybe most of the questions.
Shoot straight
