I know what tuned bow is by definition, but it’s the nut behind the trigger element. There will always be some human error in it.I think you're both misunderstanding the meaning of a tune. An in-tune bow simply means the arrow comes off the rest straight and true, in my case the cam timing was slightly off and it was kicking the arrow up. It has nothing to do with what your grip is like or what kind or release you use. If you're not putting any torque on the bow during release/follow-through it doesn't matter what your form is (you can literally shoot a bow without your arms!), but if you're "tuning" your bow to compensate for a bad habits or inconsistent form then you are magnifying issues instead of solving them.
