Great plot :)
I've a dump of the SPI transfers during a night taken with the logic
analyzer... but have found no time yet to process the dump to extract
the transfers. Of course it is easier to take it from the serial port
data :)
The adjustment looks quite closely related to the temperature.
Regards,
Javier

It appears to make an adjustment even before lock!
