"Hence, most manufacturers today tend to "overdry" or "overshrink" the board slightly, before installation, in order that the board will swell up again after installation, and hopefully maintain that curvature for a reasonable length of time (many years). Because the soundboard is restricted within the walls of the piano's case or rim, any taking on of moisture or expansion after installation will increase the curvature of the board, as the board has noplace else to go." Wow. I'm not sure I'd put much faith in anything this guy has to say. "In addition, much of the wood in a piano is laminated, so that layers of wood overlaid over others help restrict or restrain each other from much dimensional change in the areas that matter. Even a piano's soundboard and pinblock are laminated." Scratch that. I wouldn't put any faith in anything this guy has to say...... Whereas, IMHO, gray market Yamahas do just fine in Florida, this guy is biased because he is pushing grey market Yamahas - and doesn't seem to know diddley about piano construction.
