Hi cookie man. I did spend time at the table. That's how I realized that edge to A is edge to A is edge to A (with CTE at the same time of course). Stan seems to get a different shot angle using the same edge to A in his three big ball examples. A good teacher doesn't tell the student "too bad your an idiot." He tries to explain the problem areas in a different way until the light bulb comes on in the student.
