Anyone know how the Satellite servers define a file when checking the sync status?

When I do a "zac cdi ss", all of my satellite servers come back with a number of files and a percentage of sync status. This issue is that the "total" file counts are different for every server, and they seem to hang around 2300-3300 files, but I know I have single bundles with more files than that.

What do these numbers mean, and why don't they match?
