not really.
you mentioned that your in+out were about the same.

while you *could* send the article out to each and every peer, if you have
reasonable peers, you won't (because they have other peers sending them
articles, also). on an typical news server, that has similar peers, the in
and out will be roughly the same.

in fact, ignoring end-user traffic [1], the aggregate across all Usenet sites,
the in + out will be _exactly_ equal.
