[Elecraft] Reported RX Frequncies in WSJT-X?

Looking at WSJT-X 1.7rc2 ALL_WSPR log and seeing RX frequencies such as
14.0971282. Seems like too many digits unless reporting 10th of a Hertz as
in 14,097,128.2 Hz. Perhaps this is calculated as an average over the RX
window?

Looking at the log for RX over 500+ RXs, I find the RX frequency range is
206Hz. Actual TX 14,097,037 and average RX at 14,097,110, or +73Hz.

I have a GPSDO managed PC clock as well as a GPSDO managed frequency
oscillator in my K3S transceiver, so my regulation is pretty tight.

What are the major components of the deviation in reported RX frequency? I
posted on WSPRnet also, but one seldom gets replies there on any posts.
