That'd be the first 153 or something similar ;P and that ELO ranking is nuts, idiotic if you ask me ;P
You can practically get better ranking by just losing to the best and winning over those similar to your own rank.

However you can lose rank when winning battles against newbies if you're up against them.
It also ups your rank the more you play, even i you had massive win/lose ratio with around 50 matches, (3 and above) a 1.14 win/lose ratio can be alot ahead of you if he has alot of matches played.
It's just bad, really bad.

That, and the ranking is somewhere in 1.96 version ;P
