Gee, that looks like the most universally problematic part of Steinway, and other largely panel supported crown, scales. How can there possibly be tonal problems in the killer octave? Must be the plate casting. As I periodically repeat, I find this phenomenon to not be obvious in low compression and adequately supported RC&S systems. I still check now and then, but find the difference, if I can detect any at all, to not be worth the trouble to deviate from the straight line on a new RC&S board. On an original board, it's likely obvious enough to be worth the trouble. I think it's primarily the soundboard. I would posit that it's factory work, whatever the soundboard panel structure. Efficient factory forefinishing has to presume much too consistent a belly structure. Thoughtful deviations from a straight line require time and care. I don't think it's primarily the soundboard.
