[O.B.Left]

Try keeping your elbows close together at address and all the way to the top, like Hogan suggests in 5L, and you won't have to move it. Then make sure all the pulling is done by pushing the right shoulder.

This is a lost point for most. There is no left arm pull for any strokes that include #4 pivot power. For a Pull Minor Basic Stroke a one accumulator stroke that zeroes the pivot yes you pull the left arm with left arm muscle . But for other strokes the left arm , the #4 accumulator is moved, thrown off , by the pull of the Pivot , the left shoulder specifically since it attaches to the left , which is directed and powered by the on plane push of right shoulder and before it the hips . Assuming ground up, swinging from the feet.
