I think that there is already a feature in Gnus where the backend may
report the number of unread messages for each group.  But the
frontend part of Gnus doesn't use it in the group buffer.

I think if you just change the code for the %y spec in
gnus-group-line-format to see if the backend has told you the right
number and to use that number in lieu of the current estimate based
on min and max article number, then you should be fine.

Alas, I don't know what exactly is that mechanism which allows the
backend to report the %y number directly.  Simon?  I think you were
the one telling me this.
