you'll find with trad archery and people, books and videos its all pretty much for refrence only so stupid comments yeah maybe but nothing should ever be heart felt or taken personally.
its an individual sport so some people shoot with 2 fingers some use just their thumb. one guy anchors at his ear lobe and another uses the tip of his chin, I'm always less accurate with RW feathers than I am with Left wing but currently hunting with Right bevel broadheads matched with LW fletch because I learned not to listen to what other people say sometimes..
goodluck solving the problem sounds like you already nailed it.
