If the articles ever get out of sync, then the group command will report back a different "high watermark" number. Then, and only then, would it make sense to sample the posts to get a bearing on a future sync. Polling 10 of the latest posts from each group "just in case" seems wasteful and unwarranted.

Meaning Newsbin reads 10 posts it's already read. It does this because some servers can get out of sync and their post numbers aren't exactly the same. More than likely the data is already in the DB and the failure is that it's not actually adding any data to the database.
Here's what I wrote in my first reply. Perhaps you didn't understand. Newsbin has a small overlap between the last header download and the next. When you have a dead group, it means it's downloading the same 10 posts over and over.
