You can click on the "Previous Team" button to see other peoples and the other teams score. You will see some people are hitting 30000, I have hit 30000 multiple times. If you start with a win and no one is on your team yet...and you win quick...this is possible.
Take it easy, boys. Xd This isn't a contest for me. I think I'd lose my sanity if I tried for as many points as you guys do. I only do about two teams a night...
