Your ratings and stars are completely dependent on your rank in any particular contest. If you are solving one question in every contest and suddenly a contest was so easy that almost everyone(majority) solved 2 problems then your percentile will be lower and ratings will decrease if your performance is lower than your own performance in last attempted contest, but CodeChef computes percentile with a different formula.
