**********************************************

The Zinner concavity is a constant just as a flat table is a constant.

Reed performance is somewhat more forgiving because of a concavity - the
concavity's purpose to accommodate minute variables and instabilities
inevitable in any reed, prepared or not.

Flat tables have indeed always exposed the idiosyncrasies of the reed more
readily.
