  Yes & and  new rib crowned board 2 to 3 MM  ( which is aprox. .080 to .125 
thou) Ok,in this case I vote  both board & plate  change significantly when 
the tension goes on &  when it comes off.
 
 
affect more than just the two notes on either side?   I have measured 
soundboard drop under  tension, and it isn't uncommon to see them drop .050" 
when the 
piano is  chipped to pitch.  Some more (such as the Chickerings with the  
inner 
rim), some less (Steinways and Baldwins), but there is still a lot of  
movement 
up and down. 
Regards,
