Nicely done Earl, it is nice to graphically see the curves. It makes one question, what are your goals and what is actually desirable?
Sometimes, I think that we conform to what to have available. I'm use to a wall, I think that I like a wall, I like to prep to a wall and then confirm sights if required for a longer shot then break the shot.
The reason that I bring this up is that there is a saying going around in some training circles that says "knowing is a deterrent to learning". In other words if you're not open to new ideas you will be stagnant in your true learning curve.
