CodeChef's Broke Rating Changes

Hii

Recently I resumed giving contests on Codechef and I noticed something very strange. If you look closely at the standings and the delta that they get after getting that range, you will notice it. For example lets take the standings of yesterday's Starters83B (Starters 83B Standings).

  • Rank 2: 3★jointquad (1797 --> 4★jointquad (1879) +82 Ratings
  • Rank 5: 4★ryotori (1859)--> 6★ryotori (2262) +403 Ratings
  • Rank 6: 3★ohameow (1723)--> 5★ohameow (2104) +381 Ratings
  • Rank 9: 4★moscow_wale12 (1917)--> 4★moscow_wale12 (1988) +71 Ratings

Comparing this to CF's rating pattern, you will find these changes strange. Someone is getting a direct jump from lower 4star to mid 6star in just one contest and someone who scores even better doesn't even get a star change. It seems unfair and weird.

Though ratings doesn't matter much to many people but sometimes you feel bad when you get such a less delta compared to people below you getting direct upgrade to 6star in just 2 contests.

Can you explain these changes? I think earlier it used to be better...

Btw Starters 83 had some really great questions.
