If a person performs better than the previous one his rating increases ,its very good.
But if a person does not perform better than the previous one his rating decrease ,I think that this decrease
should not be there but it should be constant ,i.e, if a person does not perform better than the previous one
his rating should not be affected and remain the same as previous one.
Some people make new id’s so that their previous id’s rating does not decrease so making of 2 id’s by a person increases i think.
Some people don’t do contests because they think that if they will perform poor then their rating will decrease.
So, I just wanted to say that this system should be removed and rating should be constant for poor performance
