No, I don't see how, but you've got me curious. In the interest of getting
some real figures, I'll try to get to working out the difference in loading
between 435 and 440 this evening to try to see just how critical this is. 
Incidentally, It's way too late to cause early failure of a soundboard built
prior to 1916, whatever you do to it. %-)
