The multiple fluid pressure control system further includes a sensing means for sensing and signaling the completion of the dual modulated increases in fluid pressures and a pressure cutback means which is triggered by the sensing means signaling the completion of {HEAD ~ the dual modulated increases} in {TAIL ~ fluid pressures}
