I think so. Since there is pretty conclusive evidence from Dr Sanderson
(and others) that the majority of that pitch drop is from plate
compression, and some supportive shade tree logic and soundboard deflection
math of my own that supports it too. Strut placement and such would
probably make differences too and, as Don said, full perimeter plate, but
in general, thicker iron bends less under a given load. Nothing here that's
convertible to numbers exactly, just a general fudge factor to consider.

The name on the plate. If there's a "K", two "L"s and a "B", add 30%. <G>
