Maybe it depends on what you're pushing. What I mean is, if you're pushing against pp1 (as a swinger) instead of the club, then aren't you just further accelerating the left arm, and thus still swinging via cf? In that case, you aren't accelerating the club both radially and in a linear fashion simultaneously, even if you feel a pull and push simultaneously, right?? I believe someone posted something to that effect here before, but I'm not sure.
