So let me introduce you the best rating system which i have ever seen. So you guys must be thinking about the best codechef. which has the best rating system. you guys are smart.

So in the previous starters i found something very good. see this person had got 1st rank globally in the last DIV 2 round and his ratings changes from 1752 to 1934 an increase of 182 where as this person had 5th rank in the contest and he got from 1768 to 2239 which is basically an increase of 471 and he became a 6 star coder in a DIV 2 contest whereas the first person wasn't able to become even a 5 star.

And now see this, this person had 13th rank and his rating changes from 1721 to 1731 which is a massive increase of 10.

I would suggest atcoder, codeforces, topcoder, leetcode etc.. to change the rating system and follow codechef it's the best.

i would like to hear everyone's suggestion on this topic. Do you also feel that codechef system is too good ?

After that, the rating changes are quite less. This rating system is good when you are having a lot of rated contests on your platform. But it's not the case with Codechef. They set only one rated contest for Div1 users in a month. So even if a 5-star coder whose potential is 6 star, will have to participate in at least $(2200-2000)/30 = 7$ (approx) contests or basically, he will have to participate for 7 months to reach 6 star. And this is a very long period. CodeChef_admin should think about it, either increase the frequency of rated contests for div1 users or allow higher delta changes in a contest. The current rating system is just trash as proved by the above examples in the blog.
