Bill, think about it for a moment, isn't that exactly what you would want
your secondary calibration lab to do ?

If you use the 3458A as bench-instrument, you want it to be stable for
multiple years so you save on calibration cost/cycles.

If you use the 3458A to compare your josephson standard to the customers
Fluke 73x, you want rock steady short term stability, but the absolute
precision doesn't really matter, as long as it is stable.

Just because _you_ don't need it, or see the point, doesn't make it "BS".
