A thought...... Answered a post recently about nock hght. Clarified answer , I hope. Last 30 years at least with every new bow it has been the same process.
Nock Height. Never shot below 3/8" never over over 5/8". Half it and start at 1/2", see what bare shaft does.
Brace Height. Manufactures recommendation. Example; 8 1/4" to 9" Half that...8 3/8, See what bare shaft does.
Rule of Half. You all do the same? Similar? Completely different?
I pretty much tune by this rule also but, don't bare shaft. I predominately shoot AD Trad Lites so, I just change the point weight 'til I get good flight.
