I thought Accum #4 is the left arm/shoulder & if I'm reading it correctly, it is one of the 22 components of the basic motion curriculum. There is no pivot, no shoulder turn, so the way I read it you have to take the lag (maintaining the pressure points) back towards the ball and down plane from the ball with either the #1 or #4 accumulator. I sure do hope I don't have this messed up or I will have to reincubate some stuff. Let me know guys...TY
