I sure wish there were waterfall plots of these panels. Bit of a pain
to set up a test where all else is equal but it would be very interesting.

I am convinced that the stiffness of the system from the stators to the
frame to the floor to Terra firma is more important than we realize.

For those interested here is a link to an ESL 57 plot.
