I'm not sure i understand all you info but I would just start around 3/8 high and go back to paper tuning until you get it right. What kind of rest are you using btw? I also would download eastons tuning guide if you havent already. Its a great tool to tune with. It's at www.eastonarchery.com

Hope this helps.

P.S. maybe you could post some specs about your equipment too?
