Do you gentleman have your knock point with the arrow level when resting on biscuit? I've been tweeking mine and have it pretty close to proper flight. I've found that when people say only move it 1/32" at a time they were not kidding. When I tried to tune mine the first time I tried to use the marks and the pattern was all over the place. I'd like to add some sort of micro adjust to the biscuit.
