"But if your magin for error is outside the discrepancy in choosing the right v. wrong pin......this exercise won't do you much good."

The weird thing is we are both "right". I was "right" that I wasn't imagining what was happening to my arrows at those angles relative to my expectations. You were "right" about the shots being taken when thought about in terms of purely "ideal shooting" or dead on shooting. I understand and I take alot from these posts. I am always in a mood to learn and grow. No hard feelings, thanks for the input and dialogue.
