[Elecraft] K3: Use AM SYNC on WWV to calibrate DDS?

AM-S in FW 3.97 works great. I notice that my frequency displays 15.000.024
when tuning in WWV on 15MHz and 10.000.16 on the 10MHz signal. (Happily, the
displayed frequency is the same on both "sidebands.") The ratio of the
15MHz/10MHz received frequencies is equal to the ratio of the 24Hz/16Hz
difference between the displayed readings and the "actual" signal
frequencies (I trust WWV!).

Is there a lesson here that I can use to improve the frequency calibration
of my K3?
