Same effect found not just wid carpet but other materials. Capacitance store energy and release, energy induced into conductor. Release time constant, but time when discharge reach signal carrying cable depend on distance from dialetcric (carpet) and conductor. So effect is time smear. Long distance is bad result. Shorter distance, prefer less than 4 inch is best result. All this observe with test instrument.
Now I go put head in ice block.
