Carrot also adds a column showing the delta required to rank up. The delta calculation is done in real time.\n\n**For a finished contest**  \nCarrot displays the final deltas of each contestant in a new column and shows their rank change, if any, in an adjacent column.\n\nFor both active and finished contests, Carrot displays a column for performance, the rating at which the delta would be zero.\n\n## FAQ\n\n#### How does it work?\nCarrot runs in the browser and fetches all the data it needs from the [Codeforces API](https://codeforces.com/apiHelp).  \nIt then calculates the rating changes following the algorithm published by Mike Mirzayanov [here](https://codeforces.com/blog/entry/20762), slightly modified so that it matches the current CF algorithm. This updated algorithm is adapted from [TLE](https://github.com/cheran-senthil/TLE/blob/master/tle/util/ranklist/rating_calculator.py).  \n\n#### Is this better than [CF-Predictor](https://codeforces.com/blog/entry/50411)?\nNot necessarily. The CF-Predictor extension communicates with a server, while Carrot fetches data and performs all calculations in the browser. So the network usage is significantly lower for CF-Predictor. However, Carrot is ~~100% accurate~~ (see [#18](https://github.com/meooow25/carrot/pull/18)), it works in real time, and it shows performance values.\n\n#### How is Carrot fast enough to calculate rating changes of every contestant in real time?\nFFT. The answer is always FFT.\n\n#### I found a bug or would like to request a feature.\nReports are welcome, please [open an issue](https://github.com/meooow25/carrot/issues).\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fmeooow25%2Fcarrot","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fmeooow25%2Fcarrot","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fmeooow25%2Fcarrot/lists"}
