CF Calc (https://tahsina13.github.io/cf-calc/)
Yet another Codeforces rating calculator! Want to know what your delta would've been if you had done slightly better? Put your worries to sleep without having to worry about contest rules or calculating points and penalties by hand.
I created this rating calculator because cfviz, the de facto Codeforces rating calculator didn't have some features that I wanted, mainly a scoreboard to edit solve times and penalities without having to worry about ICPC vs. CF rulesets and a way to easily search for contests.
Rating calculation was done using the formulae in this blog by Mike Mirzayanov. Compared to cfviz, you might get different results for Educational Rounds. This is because these contests are only rated for Div. 2 participants, Div. 1 participants count as official participants. Cfviz, as far as I am aware, does not filter out these contestants. In practice I have found the results to be closer to the actual Codeforces deltas.
Seamlessly switch between light mode and dark mode.
Search for contests by name without having to look for their ids. Many thanks to junegunn for creating fzf and ajit for creating a javascript port of it.
Edit problem scores and penalities for both ICPC and CF styled contests without having to worry about all the rules.
View your submissions to problems directly without having to go back to Codeforces.
