Hi , i gave a contest on codechef after a long time yesterday so maybe i have missed on community updates, but yesterday i got a rank 29 in div4 and my rating increased to 1400 but i saw a person with a rank less than me his rating was increased to 1740 , is this a bug or an intended feature as i saw people with 0 contests reach this rating yet people who have given>=1 contests don’t (similar happened with my friend a few days ago)
also i dont want my rating to be increased i just want to know the reason for this 
sorry if this is out of place
