Yep, you guys hit it exactly, and George was around to know from experience. I was there for the end of the field archery era so I got to see some of this too.
There is nothing wrong with face walking or string walking. Nothing. Except it is against the rules in that game.
It is not the same as instinctive. There is no reason to "walk" if you are shooting instinctive. It is a method that is used with point on (sorry, not gap.. edited) shooting, using the arrow point as the front sight. period
The problem with the game, as many see it.. me too, is that every time you add a sight, or gizmo, you can... can... improve accuracy. Is it fair for me to compete against someone who is obviously shooting using a sighting method ? I think not.
That's why the rules (for some games) say no. Course, you always have those guys that need to win so badly that they have to cheat and not follow rules.
Again... it isn't bad or wrong. But it is different and should be compared against like styles.
Chris.. George is right on... it is two different games. not two scoped rifles. one scoped and one with iron sights is more analogous. In fact, using instinctive shooting, you don't even use sights.
