Funny you mentioned that since I just got knocked back down to A+ by a Hitomi that cleverly delayed his strings the entire fight. Shouldn't take long to get back up there XP
Congratulations! I reached S- rank some weeks ago, and at the beginning i switched continually from A+ to S-. Currently I haven't done great progresses (now I'm around 53500 points when the S- rank arrive at 51000). So I'm arrived at the point where I can level up just improving effectively my skills (but I like this ).
I'm not a real S Rank either. Just the fact I've managed to come this far online just feels great enough : D I'm expecting to be knocked back to back between A+ and S- for a while, so it could take weeks for me to get to a regular S <.< I'll still hang around in Ranked of course. I only have 36 matches to go until I unlock Alpha XD
Anyway now that your rank is S- prepare yourself to a negative side effect: a big number of players will refuse to play with you in the lobbies... It's funny like they think to lose still before to see your effective skill and not just a letter; in addition to the fact that personally I enjoy more play with most skilled people, rather than win continually against opponents less good.
