[pianotech] grand bench regulation again

[David Love]

The key bedding changes and so it depends.

    I can't remember -- when a grand action is removed to the 
bench, is the dip usually less or more than it was in the piano? 
Or does the key height change, thus changing the dip?  If the 
dip is more or less, that must mean the keybed is not flat 
front-to-back (I'm assuming a level, flat benchtop).
