Biffer, most of us shoot targets by the bunch. A five, 25-50-100 and we think in those terms when on the line.
The top shooters in all the shooting games think in one target events attacking each one individually no matter what it happens to be.
New shooters are like sponges and will soak up information both good and bad. The old experienced hand only wants a quick fix for that one to two extras, IF, it fits in with his way of thinking or learning new techniques. There are several old sayings that are true and apply to your questions. "Never too old to learn." "You can sometimes learn from a dummy, but, only if your listening." "If you think you can or can't, you are probably correct." Maybe not exact quotes but close enough.
Not everyone that happens to have the ability to do great things can teach others how it's done or how they do what they do. The ability to teach is a gift, just like the ability to perform is. Some can and some can't convey that knowledge in terms thats understandable. After watching Phils video, he's a gifted teacher and shooter in my book!
