    I do not know of any way to predict the panel stiffness of a =
compression-crowned soundboard system. Even if a formula were developed =
I suspect the many variables would degrade accuracy to the point of =
uselessness.
  Well... obviously you must have some way of finding the overall =
stiffness of the CC board...  or you couldnt know an RC board could be =
made stiffer at all.. let alone for any particular comparisons sake.=20

Ah, that.... While I can't predict the stiffness of a =
compression-crowned soundboard through the design process I can eassily =
find out how stiff an existing panel is. Simply apply a known force and =
measure deflection.
