Hope that helps.
Actually I believe it is 1500 positive points for eleven dots. Once you hit 100, if you don't have any negs, it will go up to 2 dots. Here is a little chart:

1 dot: you start with this and requires no points
2 dots: 100
3 dots: 200
4 dots: 300
5 dots: 400
6 dots: 500
7 dots: 700
8 dots: 900
9 dots: 1100
10 dots: 1300
11 dots: 1500

I don't know how it works for mixed pos and neg. I think you have to have that many of either of them.
