You are reading the FCC rules correctly - that is the maximum of gain
allowed. And you are correct that our discussion focused on reducing the
variability of how companies interpret the volume control requirment by
having a standard metric by which to assess all products, and requiring a
certain amount of amplification above that specified level.
