Interesting point.  Once again the laws of physics must be
considered.  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
