Once you bare shaft and get it perfect, the. You worry about nock tuning if fletch clearance becomes an issue. That’s my understanding. Every once in a while you get 1 or 2 arrows that won’t group with the rest. That’s when I would start screwing with the nock alignment.
That's carbon arrows for you.
Also the reason I fletch with the same 3 colors. If an arrow will not group with the rest I can twist the nock to a different fletch as my coxk.frather and see if that brings it into the group.
