You have the right idea on walkback tuning. Start at say 20 with your 20 yd pin and then shoot at 30, 40 etc., all with the 20 yd pin. Your arrows should fall in a vertical line. If they fall down and to the left, move your rest in. If they fall down and to the right, move the rest out. We're tlaking 1/16" or less per adjustment. Once they do fall vertically, broadhead tune.
Shoot a broadhead or two, then a field point or two at 20 yds. If the BHs impact left of your FPs, move the rest in very slightly. Do the opposite for BHs impactinr right of FPs. Same goes for BHs impacting higher or lower than FPs. If the BHs are higher than FPs, lower rest or raise knock, etc.
Once BHs are impacting the same as FPs you may need to reset your pins.
