Hello to all fellow coders. As Carrot seems not to work, I decided to try to create a rating predictor myself. Here it is.

This is a fully working app, trained to give results for all ratings. A percentile is the place in the contest divided by the number of participants.

Special thanks to github.com/awinnnie (she's a wonderful, pretty girl) for help.
