Cecil, efficiency depends on what your objectives are ...

I guess that is why there are 20 definitions for "efficiency"
in the IEEE Dictionary. One needs to state one's definition
of "efficiency" at the beginning of the discussion to avoid
confusion with all the other possible definitions. For instance,
Power Company EEs have a different definition of "power" than
do physicists, politicians, and priests.
