Rick, My arrows are currently in my shed,holding a straight edge against the string & rest I get 7/8". My regular old run of the mill Drop Zone is working with plenty of room to adjust either direction.
I know when the shop placed my stuff on the bow he lazer centered the rest and through walk back tuningI tweaked it towards the riser a touch.

I'm not sure what that says about my arrows, set-up or hand position, but I did it.

FWIW, the windage line is set on the seventh adjustment line from the right side of the rest if you are holding the bow.

There is one more windage hole left for my rest, the holding bolt is currently in the second from right hole.

Good luck with it, let me know if this helps.
