I have observed the same. I just went back to the official gnus version
(5.6.45) and looked in those newsgroups and found no messages that I had
missed. So my guess is that pgnus just makes an error in the initial
article count.

I had it again and it appeared that there was a message in this newsgroup
that had followups in a different newsgroup. So could it be that in the
initial count the whole thread was included including the messages that are
not in the first newsgroup?

I've seen that as well.  I've also found on occasion that my scoring
rules end up catching up the entire group.  I use adaptive scoring
with an expunge and duplicate suppression as well as some aggressive
manual scoring.  Still, I find it a bit disconcerting when an entire
days worth of news is eliminated that way.  I find a fairly easy, if
time consuming for certain groups, check is to do a C-u 0 M-RET on the
group.  That gives me an empty summary buffer.  Since I ordinarily use
threading, I do a T T to turn threading off and then a C-c C-s C-n to
sort by article number.  I haven't yet found anything at the end of
that buffer that I actually wanted to read anyway.

I have observed the same. I just went back to the official gnus version
(5.6.45) and looked in those newsgroups and found no messages that I had
missed. So my guess is that pgnus just makes an error in the initial
article count.

No, I don't think so.  The amount of vanishing articles would mean that
there's a large-scale cancel or supersede attack, and it's quite likely
that I would have heard of that. ;)

It doesn't happen in mail groups, so I assume it only happens to you
in news groups?

Is it possible that the messages in the group have been canceled
by their originators, so when you enter the group there is nothing
there to read?  This would cause the symptoms you describe, but would
not be the result of gnus marking the articles as read.

After that, the unread article count is zero.  This happens only very
sporadically, and I haven't been able to track it down yet.  Any ideas?
I haven't observed this with v0.96 or mail groups, BTW.
