I agree: "Scuffing" is a more accurate word than "scruff" to describe a sliding blow that isn't able to rebound directly in the same plane of motion in which it approached its target. Like scuffing your shoes; Scraping, abrading, grazing. Wouldn't this type of blow also casue the hammer to stay on the string longer and affect various partial strengths? Of course, not only overstriking results in scuffing but other things such as loose pinning, action rails that are not perpendicular, poorly anchored hammer flanges, warped hammer shanks, and the list goes on. All of these add to inefficiency and lack of control. Faster wear of hammers, and perhaps wear of bushings could result from this type of hammer boring. Boring that creates overstriking so the hammer shank can whip backwards does not take into account soft blows that have less whipping or bending of the shank. I have changed overstriking hammers in action rebuilds to 90 degrees, both in uprights and grands, (adjusting for strike points) with improved results.
