I set up a lot of trad bows for folks in my community and the 4H kids I coach. A lot of custom and factory bows are cut past center, as posted above, so the shaft is on centerline w/string, or in a little too much. YOu can then use pads, stick on rests or leather etc., to build out to center. I use a center shot tool, like on wheelie bows. YOu can easily tune, shoot in and get your bow shooting, often with a wide variety of shafts in a few minutes, alleviates a lot of the frustrations you hear people venting/discussing on hear about. I wont shoot any of my bows off the shelf, I usually induce too much extra wiggle in them that way. PM me if I can help some more.
