Thanks guys for the kind words. It means a lot. Most guys take one look and think I am measuring the lead. The goal is to learn to keep both eyes on the target from the acquisition of the target to the end of the follow thru while knowing where your barrel is. It helps Gil Ash does something similar. I think the correct yardage and lead helps.
I do not know why my lead is short. One winter, I practiced a 42 inch lead. That spring could not hit anything from station 4. Cut the lead back to 21 inches and hit almost everything in the middle of the field. I will not let anyone describe my swing to me. I do not want to think about it.
My forty yard lead is twice my twenty yard lead. Whatever I am doing, it is very consistent.
