Rating predictor for Codeforces

Carrot: Codeforces Rating Predictor & Ranklist Enhancer

'Carrot' is a dynamic Chrome extension built to enhance the experience of Codeforces users. It provides real-time analytical data for both active and finished contests through updated ranklists. For active contests, Carrot predicts the changes in ratings, calculates the required delta to rank up, displays them in new columns, and offers real-time calculation. Finished contests feature the final deltas, enabling users to view the rank changes. Carrot also presents a unique 'performance' column that showcases the rating at which one's delta would be zero. With the freedom to toggle columns as per user preference, Carrot ensures an organized and relevant data display. Despite running entirely on browser-based communication, it delivers high accuracy with only minor exceptions due to the new rating system.

Extension summary

Carrot enhances Codeforces ranklists.

For an active contest: Carrot calculates rating changes according the current standings when you open the ranklist, and displays them in a new column. Carrot also adds a column showing the delta required to rank up. The delta calculation is done in real time a̶n̶d̶ ̶i̶s̶ ̶1̶0̶0̶%̶ ̶a̶c̶c̶u̶r̶a̶t̶e̶ (see note below).

For a finished contest: Carrot displays the final deltas of each contestant in a new column and shows their rank change, if any, in an adjacent column.

For both active and finished contests, Carrot displays a column for performance, the rating at which the delta would be zero.

Each of Carrot's columns can be toggled according to your preference, so as to not clutter the ranklist more than you would like.

Carrot communicates only with the Codeforces API and runs entirely in the browser.

Note: Since all required data is fetched and processed in the browser, Carrot is not ideal if you have a low data cap on your network. If so I recommend using CF-Predictor instead: https://codeforces.com/blog/entry/50411
