Carrot

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.
