Jeff, As I mentioned, I feel it is a combination of different things. When I was with Young Chang I confirmed that at that time they were using very stiff, aggressive wire and the string bends were not settling down. In the capo bar area especially, the radius of the arc held by the strings at the bends was very large, and pounding (or hooking, or pushing with a Strate-Mate) settled them down sometimes 1/2 step or more. Then pulling the strings back up to pitch would move the bend enough to make it all happen again, though not quite as much. But once strings are settled, I agree that friction at the bridge is a continuing factor that recurs over time, and getting the tension to pull over the bridge is helped by the hard blows. In some pianos there is a lot of friction at the capo bar bend as well, and those pianos require a mean and nasty attitude on the part of the tuner to knock them into submission. :-> Another sort of related factor is the small tuning pins, with the over-turning of the pin a fair amount helping you to un-twist it into a stable position. The pounding may not do much here, but the over-pulling does. String stability is a full class seminar, for sure.
