Characters without faction are not counted, that's another 2000+ testing chars that are not present in this report.
Of course these numbers include alts, but I believe that doesn't change much concerning the overall balance of players.
As for BB/Family, my opinion is that BB were composed by a main Russian force which immediately united and got out to the city together pretty early, while the Family is composed mostly by a lot of single players that took time to discover the game and organize. What I've seen from the Family recently tends to confirm that their preparation time is reaching the end and their fight for Phoenix should start soon. However, I doubt that they can handle the pace of Lawyers and V-Tec, which are almost always ready to engage anyone.
