Drastic decrease in rating

In yesterdays July Lunchtime due to lack of time i was able to made only two submissions, one got accepted and the other one got TLE, and my rating decreased by more than 100. Can anybody help, why such a decrease in ratings

Yes, because your rank was very low

Ratings are given based on the ranks. Your rank yesterday was 7190. Compared to people of your rating, people were a bit ahead of you. So such decrease in rating

Because as per rule if you are ranked low they gonna decrease your rating…
