Explain your thinking a bit more in detail please :) Well, the pianist is getting feedback from fingers and ears. So if a note is harder to play but doesn't generate more sound as a result, it will be sensed as unevenness. This is what happens in the case of uneven FWs or BWs. But suppose the FW was perfectly smooth, the SWs are smooth but there is still some variation in SWR (which there is likely to be). Then there will still be some unevenness in the reflected inertia of the hammers, but the feedback from finger and ear will be better correlated. A hammer being accelerated faster (higher SWR) will feel heavier, which it ought to. The same force will result in less acceleration, but for a longer time, which works out to the same final energy in the hammer. But you can only get there if you can eliminate the "noise" of uneven key inertia and BW. -Mark
