As of your first question, i solved this one a bit too long ago... i'll look into it and update this post later.
Also, this thread helped me when i had WA2 http://acm.timus.ru/forum/thread.aspx?id=27267&upd=634549324304261511 — if the user has read the tweet, but can't retweet it, he still counts towards the people who know. Maybe that'll help you.

UPD: okay, i get it. Your 999..9 user is not in anyone's followers list, so he shouldn't retweet the message from anyone. 444..4 and 55 can repost 999..9 if he posts something, but he never will, cause he's not a follower of anyone.

Also, retweets.

Some of those retweets (third one only, in fact) exceed 140 symbols, but this is just debug output. Those messages don't get retweeted and don't participate in further retweeting. Still, that user has read the tweet, and so he acknowledges its existance.
