It also shows that a signal "more accurately" represented as a 30Khz BW
at -50dB with a 3KHz RBW does not have a BW equal to 30Khz + RBW when
measured with a 30Khz RBW. That's what I was after, it carries instead
the 6x-10x relationship.

All this really tells you is that the shape factor of each of the 
filters in a particular analyzer are approximately the same.
