I note that even while some in the standards community are adding cost in their efforts to systematically remove variation in measurements, no one is then passing on the benefits of this improved measurement system to manufacturers & their customers by accordingly raising the allowed emissions limits.  Wonder why???

Because the initial approach from the metrological theory was that MU involved tightening all the limits. So it was decreed that the existing limits were set taking MU into account and didn't need to be made more stringent.

Incidentally, the main object of studying MU is to control and quantify it, not to reduce it unless it's clearly out-of-control.
