“You are finding the offset, for YOUR bow hand size, YOUR angle of grip, where the offset away from the instant center, equals the horizontal offset for your sight pin, when you TORQUE the bow hand any angular amount. If you TORQUE your bow hand HARD left, and the sight pin moves say 3/32nds LEFT...and you have to swing your bow arm to get back on target, regain sight picture....YOUR magic distance for moving the arrow rest frame forwards or rearwards...will result in an equal and opposite offset of also 3/32nds. When you swing your bow arm to get back on target (while torqueing the bow hand hard left), the arrow returns to the original line of sight, before you torqued your bow hand. The best way to figure this out is GO shoot, and move the arrow rest forwards or backwards, until you can shoot the bullseye with ZERO torque, and you can shoot the same bullseye, with medium TORQUE sideways from the bow hand.“

Ideally, you’d want an arrow rest with an overdraw that you could adjust. But most drop away rests are fixed.. so running the scope closest to riser on hunting bows ends up torque tuning the best for myself and everyone I’ve ever seen on various internet forums(regardless of make and model). Not sure why, it’s honestly confusing af.
