Here is another thought. Wouldn't it be nice of the Makers put as technical info in their technical manuals, the factory target down weight? Following that wouldn;t it be in their interest to mention a target up weight? Thus if they said a piano left the factory at 53g downweight and we measure it at 56, we know friction increased, because what else would make the DW go up? Still though 56 might be acceptible. Also I wonder why a simple differnce between DW and UW can't be used. At least for friction reducing attempts. I think it (the difference) is divided by two because levers are involved, but at the keyboard the first "reading" is the actual difference. Why have to mentally divide that by two and remember that also? So would it be wrong to say? "since FW of 10 is acceptible, then a diff of DW and UW of 20 is acceptable but getting up there." ---ric/2not
