I never cared for walkback tuning. Too many varialbes in shooting form that can give you misreading. Ive seen guys tune their bows forevery trying to fix a problem that could have been solved real easy by eliminating hand torque. Besides, todays rests are so easy to set, Ive seen little use for it. Creep tuning is ok fortiming when you first set your bow. But once you got the timing down you should never have to do it agian. That is if you mark your cam/cams with a sharpie, which I highly recommend.
