MK- Out of the house, the target is traveling about 21 yards / second and your estimate of 3/4 of a second is about right. But, you failed to appreciate that shooting within 3/4 of a second is not fast shooting at all. To me, it seems rather slow.
Also, when you look at targets from the side it is difficult to estimate the base of the triangle. Your reference points are typically well beyond the target flight. Also from the side, it will appear that the angle targets are broken much faster than the straight away targets. This is simply a visual error.
pheasantmaster- I absolutely will never again pattern anything at 45 yards. At that pattern distance, I can look at a pattern and conclude that I could never break a good score.
