I'm just tring to keep my position in top 200, but it's really hard. Bottom line is increasing everyday, and maybe even has dramatic changing in the last week, but we won't know that.
In my opinion, top 200 is ok. Because there are only no more than 2k people take part in, and maybe a half will stop before 20th level. So it's a kind of compteting not only on your wisdom, but also patience.
Everyone is busy, we have lectures, homeworks, papers, experiments, but everyone has equal chance in this long time to finish levels. I know someone get 70000+ points in about 15 days, and, we still have 15 days, aren't we? What we should do is to find out which is important to you, then focus on it.
Maybe I partly agree with you that it's better the Leaderboard not be locked in the last week because we can give up earlier. But there will be less fun, I think. And to be honest, I only want to get a T-shirt from Microsoft:)
