Adjusting plate suspension bolts?

[David Love]

I have not tried to make a specific determination.

Has anyone determined how much the pitch changes for a given change in
bearing?
How does the pitch change vary across the compass?

Ron is right, you can do a few at a time.  Going up forces you to do more
than one at a time because you are raising the socket screws against the
plate whose stiffness will provide resistance to raising the screw.  Going 
down you can lower each screw as you go by, say, 1/4 turn or whatever and
the plate will flex only when you tighten down the acorn nuts.  As Ron said,
just do it incrementally.

Up... But since the point of this piano is to experiment and see "what
happens if"...
I'll play with down as well.
