Do You Know Which Topic Has Your Lowest Average Rating?
By deyna256, history, 8 months ago, translation, In English

I didn't know. I thought I solved everything more or less equally. And I would've kept not knowing the truth if I hadn't built a tool to analyze it!

BetterForces is like Codeforces Profile, but with numbers and charts that actually help you train.

What I learned about myself (as example): I have 23 abandoned problems at rating 2400+. I tried, got WA 5 times, gave up. Now I have a list — can approach them systematically. My average rating on tree problems is higher than overall. That's my strength. Constructive algorithms? Disaster. Need to practice that.

Works for any handle: https://betterforces.deyna.xyz/

Open source, if you want to check it out or contribute: GitHub.

Pretty cool metrics. Not sure how you would fix this, but some tags are inherently easier than others which might skew the median/mean solve on each tag.

Nicely done, But Because As and Bs are almost always math and implementation so you will find it's Avg and median around 1000s, What I think about is allowing the selection of the problems rate used in the calculation, like a range to select from i.e. 1200s to 2000s, This will prevent the calculation of As and Bs that are always math and implementation and will have more accurate readings.

I'm not sure if it's bugged or not, but it doesn't show Graphs for me. I would love to analyze that, because Graphs are my favorite.

Other than that, I love it. I think the GUI looks great

    Thanks for the feedback! It's not a bug, "Tags Performance Radar" shows only top 10 tags by amount of solved tasks, that's why u don't see it there.

    Don't hesitate to suggest metrics or something else!

The problem was not only with CodeforcesAPI restrictions; my API also had a small hourly rate limit. This has now been fixed.

Welcome to the new testers!
