  That makes sense.  But let's take our favorite whipping boy, the =
Steinway M.  As you know, when recalculating the scale, one tends to =
come up with a needed increase in gauges above note 50, pushing the =
tension up a bit all the way to the top (changes across the bass tenor =
break are another issue which I don't want to get into at this point).  =
If the Steinway board tends to be a lighter more flexible one, would you =
then be cautious about increasing the tension up there for fear of =
overloading a board that is not capable of dealing with that type of =
change?

Well, it's not an ideal world. The Model M scale has a real dip in the =
middle of the top tenor section and is generally lower than I would like =
to see it through the killer octave region. I am always cautious about =
raising string tensions on an existing piano. In this case I find the =
increase to be less bad than the alternative.

Ideally, the soundboard should be stiffened up some through the whole =
upper third of the scale--quite the opposite from the effect achieved by =
diaphragming it. When putting new boards in these pianos we do not thin =
them out along the treble edge.=20
