I have to disagree with this.  There is such a thing as pounding too hard.  I used to pound really hard, and would occasionally break key sticks and strings, although many times, the keys had a weak spot in the grain, usually at the balance pin hole, and the strings were OK but the hammers were too hard.  Anyway, I would frequently find my tunings sharp when doing my final check, even tho' they were "right on" with the SAT as I was tuning, doing unisons as I went.  I asked the list about this, and someone replied that too-hard test blows can cause strings to drift sharp.  I have since lightened up my key pounding and have almost no incidence of tunings drifting sharp.  I haven't changed my tuning style in any other aspect, so I think that was it.

  And pounding hard too often leaves you with strings creeping 
  sharp when you quit, particularly when you're lowering pitch.

  Or raising pitch.  Doesn't seem to matter, in my experience.  --D.N.
