I was recently looking at an article on piano plates that discussed this issue , the purpose of the holes on plates etc. Will try to find it since it is an interesting topic.

Subject: Plate creep
It seems like I read something about this at one time. String (frames) plates seem to creep over time. Sometimes the tuning pins are crowded against the backs of the holes. Not all of this can be attributed to pinblock fatigue. While beginning teardown of a Steinway D for new bridge caps, I noticed this and also that the perimeter bolts leave an impression that seems to creep forward and out from under the bolts. Does anyone know of what might have been published/shared about this? I am thinking of shimming the front edge of the pinblock when I reinstall it to compensate for this, but I wanted to know what others have observed. If the piano is really old, it may be quite severe.
