RC&S design sounboards do not rely on the panel re-hydrating after ribbing 
to produce crown. The crown is set by rib shape. So there appears large 
fundamental differences between the RC&S boards and the traditional English 
method as you have described it. And who ever said RC&S concepts were new? 
Uncommon these days, yes. New, no.

15-foot radius crown is not exaggerated, but rather commonly found in RC&S 
soundboards. A panel in a soundboard with that kind of crown certainly would 
have some significant degree of compression in it if it were to be 
flattened - but why on earth would anyone want to flatten it? I don't get my 
soundboards anywhere near flat after stringing.
