Does that mean it depends on the person? In another post, it talk about how good chipping and pitching by using right arm only push stroke (hitting).

For extremely short shots which Homer termed Basic Motion, we limit ourselves to our Basic singular Power Accumulator. Putting or short chip shots say. The Hitter using his Actively extending right arm, from a Push or Punch elbow position. The Swinger using his Right Shoulder in a rocking type motion say. There are options.

For longer chip shots we need more power and so we "acquire" it by adding a pivot. This Homer termed Acquired Motion. We add another Accumulator to our Basic Motion.
