A reasonable tension target is 160 pounds, I am sure you meant to 
write, and I would agree.  Not 160 psi.

I also agree that all this talk of rescaling the plain steel scale of 
an existing piano is largely nonsense.  The covered string scale can 
be greatly changed with advantage on many existing scales but the 
only way to "rescale" the plain steel is to rip off the bridge and 
fit a new one of the best shape and in the best position, and if the 
piano was so ill-designed in the first place it's not going to be 
worth the expense of the exercise.
