For all you touchweight and new-piano-prep enthusiasts out there. These are the data provided to me by a customer who just bought a new Steinway B. He complained to the dealer about it being heavy. The dealer sent a tech out who adjusted the key dip and pronounced the problem cured. The customer gave me the UW and DW. I calculated the Friction and BW for him. I can't vouch for the accuracy of the measurements but the trend seems consistent. My suggestion was that he will probably have to move the capstan, smooth the hammer weights ( or strike weights if you prefer), address the action centers balance rail pin and bushings, regulate and rebalance the action (at least).
