<P>When you make the calculation of frequency change due to change in deflection, are you also factoring in the resiliance of the soundboard? If a piano is strung and up to pitch, and you change the downbearing, would you not also be changing the load on the soundboard? Example: You reduce the downbearing and the soundboard moves up slightly under less load. I may be off base, as I don't know how much the downward load alone on the soundboard affects frequency, assuming the downbearing angle the same. </P>
<P>I would appreciate your thoughts on this, </P>
<P>Respectfully, </P>
