There's about 25 lbs of side bearing on a pin at a 10° offset 
angle. That makes about 14lb of friction between the string 
and the pin. So tapping the pin down is the rough equivalent 
of gently seating the string with a 14lb hammer. Whether the 
pin is at the bottom of the hole or not makes no difference 
acoustically, though that's the illusion and everyone's 
conclusion when bottoming pins clears up a beat. When you seat 
the pin, you're just seating the string once removed, and 
still haven't addressed the cause.
