Has codechef forgotten about updating the ratings for sept Ltime?
I think they have developed a habit of not updating the rating after the contests
unless there is a forum post asking about the same.
Admin?
I saw somewhere on there facebook page that the delay was due to the checking of plagiarism in codes.
alright 
We regret the delay. But we are investigating some plagiarism cases in the September LunchTime 2014, after which we will calculate the ratings and will contact the winners.
