I'm not really helping here, because I'm not sure, but:

1. If you look at someone with 11 green dots, you'll see that there are five dark green ones, followed by 6 lighter green ones. The dark ones are worth 100 antipoints, the lighter ones are worth 200 antipoints. Or the other way around (that's what I'm not sure about ).

2. Not sure, either... we should ask swifty... 300?
