More dip in bass

[David Love]

I'm not sure about that.  A small amount of compression at the balance rail
is magnified x 2 remember.  Also, I don't think I ever recall a problem of a
piano developing too much dip over time.  More often, it's the other way
around.

The compression wouldn't be as much as at the front rail...but I wouldn't do
it either.  I have a leveling stick that has a crown in it which I use.  If
he sets the level like this maybe he is crowning the keydip?
