Yeah, I meant that as after 1,000 wins and you are positive, but no more than a 2.0 ratio. If you go above a 2.0, then you have to use the positive room, until you fall to a 1.5 (If you fall to a 1.5).
If you are negative though, you can keep using the negative room, but yeah, maybe just until 3,000 wins. Not sure though, but I guess there should be a cap, so no one goes in there to mess with less skilled players.
