popsicle stick engineering

[Kent Swafford]

You know, when I tell people at the university that a piano was a dog  
from the beginning and that new parts over the years have only made  
things worse, they look at me like I'm crazy. On the other hand, one  
seems to always be able to get pianists to agree that there is not  
much of anything worse than a bad S&S. Maybe they just think I'm  
crazy for suggesting that an instrument with manufactured-in canine  
characteristics could actually ever be changed into a fine instrument.

Did you mean "acceptable ratio may not be _achievable_"? Or did you  
mean to say that even with a good ratio, this action might still have  
unacceptable characteristics?
