I'm trying to figure out your pointof quoting me? And, what the problem is that you are saying exists.

Because I talk about what you should do for a test does not mean that you can't do any test that you feel like doing. Why, because from performing tests with a lot of variables usually you often learn the differences that arrow diameter or weight, point shape, etchave on an arrow at impact. From that you can decide if you want to perform a controlled test. Yes, the tests are not valid in the technical stand point butfrom a real world stand point they are.
