The first is the Lag pressure swinging for basic motion but I have no figured out how to do that yet.
The second, and it was there all the time, AIMING POINT, I have never understood it and found it of no use until I reread 6-E-2.
I never understood its application was only the line BETWEEN top and trigger (#2swing or #2&3hit) That may be my problem- wrong swing aming piont (without knowing it or why) and therefore continuous search for proper swing mechanics.
