Jules Feldman asks:

My suspicion is that the relevant official took a previous list and updated
the ages without checking who was present in the town.
What can the mavens tell us?

I may or may not be a maven, but my experience with revision lists from
Lithuania is that the officials did ask about people who were previously
recorded and not present, noting their current status, e.g. died,
conscripted, moved away. That may be why the census records were called
revision lists!
