I think you can create an Excelsheet for yourself with three columns: CV version, date inservice, date outservice
and with the information published in the monthly overviews you can fill this Excel sheet.

The timestamp when the observation was published will correspond with an period in the excelsheet and so you will find the used CV version.
More interesting to know if the observer was sure about the observation or not. Other websites have the possibility to add a question mark to the observation.
Other users above noted, the Seek model is separate. It is possible to determine which observations have been made with Seek, so you can make a separate Excel sheet for Seek with the same columns and maybe one or two rows,( cause the CV model has not been updated yet for almost 450 days )…
