Perhaps the hammer is actually decelerating since it lets off. When the force that causes acceleration ceases, I think you begin deceleration at that moment. Maybe someone from physics 101 can say. But suppose a decelerating hammer made a difference, could you control it? To decelerate you first have to accelerate. Maybe then the let off should be 12.5 mm instead of 2.5 eh? --x(-;Þ
