IS4T,
Different folks/diff. strokes. I concur w/ you but realize diff folks like diff tacts. I've never found a target medium that didn't alter the way a shaft penetrated as it drove forward, so that it came to rest as it was pointed going in. I gave up on nock orientation for that reason.
OL's approach, which he quickly points out is older'n he is and isn't HIS, eliminates the headaches.
Tuning can be problematic if you torque your bow, or pluck string, or have inconsistent release. Adding in how the point plows into a target medium only made my life insane(r)
Ol's outline hsa worked wonders for me when I do my part to shoot consistently...
