Another possibility is all those SDR's sitting in unheated sheds sending
RBN spots. That, of course, would lead to more or less random frequency
errors.

Perhaps what we are seeing here is the cumulative error of the transceivers in
the chain.
The DX tunes the rig to 14023 and calls CQ, but their transceiver is just a bit
off frequency for one reason or another, so they are really on 14022.95.
The spotting station’s transceiver is also a bit off frequency, so when the DX
is tuned in, the spotter’s rig shows 14023.1 - and that’s what gets spotted if
the frequency is acquired as data from the rig. If the spot is generated by
keyboard, then more errors are possible.
So when you click the spot, you go to 14023.1 and are .15 off the DX frequency
+\- whatever variable your rig might introduce.
I don’t have the expectation that when in click on a spot that I will be
exactly on the DX frequency. I just like to land in the general neighborhood!
