Hitters pivot. The pivot however serves as a backstop or launching pad for the driving right arm. #4 is the master accumulator. It triggers the others. Do you have any sense of the #4 pressure point? Outside of my hands this is a huge feel for me. When I hit I try to only use #4, #1, & #3. four barrels is for trouble makers! I have found extensor action and a centered and stationary head invaluable in learning to use #4 Acc. If the left arm is not moving across your chest (with pp evidence of that fact) then you are probably using a shoulder turn takeaway. Most people use only two acc. (IMO) and then not always in the right sequence. Homer said a good (satisfactory?) game can be developed with just two acc's. Hope that helps. Daryl will fill you in on the details!
