Note. This is an updated version of this post. If you like this style more, please tell me in the comments.
Since tourist's breakthrough, I've received a lot of requests to update my old posts with rating achievements. However, I wasn't able to do it immediately since my method of doing it requires to download the rating change history of every user, which, in turn, requires to perform several hundred thousand requests to Codeforces, about which the website (and Cloudflare) is not happy. It took more that three days, but finally the job is done!
Below are two tables. The first one is the greatest (by absolute value) negative rating changes. The second one is the first users ever to reach some rating value. First table:
Second table:
Here is the twin of this blog with ratings below 1500.
does the list matter too much? Or why you take so much time on it?
I need to basically check each user whether they reached some milestone earlier that others or not. And for that each user's information has to be queried through Codeforces API, that takes a lot of time.
For this particular table I could probably get the correct results with only top-20000 users which would only take several hours, but with this approach I risk to miss someone.
The world is full of Tourist.
Well, yes, but at least in the left column there is a room for Benq!
Maybe you can put the 1st table in Hint, so that people can collapse it to look at the 2nd table?
Also I feel like the old table is much better; the new one is very difficult to read, and difficult to navigate (e.g. I can't search for 3700).
Thank you for the suggestion!
I am honored to be nominated by your list, I am very touched by your behavior, I believe that you are very fond of algorithm competitions, and I am the same, I have insisted on algorithm competitions for more than five years, and I hope that I can become stronger and stronger in the future.
Finally something tolbi is good at!
