I've heard of this before but never tried it. I do know that when I started shooting 3 arrows per round instead of 4, my confidence went up.
I read that Byron Ferguson only shoots 3 per round. I figured when Byron speaks, I should listen. BUT..I ain't no Byron!! So if he does his best with 3, maybe I'd do better with 1.
Since it's cold outside and I'm limited to 10yrds in my basement, I'm gonna try this.
