Hi there!
Recently after Codeforces Global Round 21 Um_nik noticed that he might be the ninth or tenth person to reach 3600 rating points, but still he did it earlier than Petr. I wondered whether Um_nik really was that attentive to know for sure how many people reached 3600 before him. As this is an objective truth or an objective misconception, I decided to simply check it. After several hours of programming and abusing Codeforces API I am ready to state that Um_nik was indeed correct — he and jiangly both broke through the 3600 mark simultaneously, being the ninth and tenth person to achieve it. I decided to get more interesting facts from the fetched information — for example, although Petr's maximum is 3597 and he hasn't got to 3600 so far, he was the second one to get to 3550 points, and this took place almost four years earlier than the Um_nik's analogous achievement.
Anyway, here's the full table. In the first column there are milestones, and in the following columns there are first, second, ..., tenth persons to get at least so many rating points, along with the specifics about the participation in the contest preceding the achievement. Sadly, I'm far from being the god of HTML and layout design, so this may seem kind of clumsy (for example, the table might be overlapping with some Codeforces interface elements), sorry for that. If you have ideas on improving the appearance of the table, or on more convenient way to visualize the data, please share them in the comments.
The last but not the least, I must confess that come of the cells still might be wrong. There are hundreds of thousands of users here on Codeforces, and I have fetched only around top-20000 by rating. It's still trendy to draw stalactites with rating graphs by deliberately sucking in several consecutive contests and performing a totally unexpected comeback afterwards (check vintage_Vlad_Makeev's or 300iq's graph for more details, even though they may argue that they failed in the contests for real), so I might have missed a strong person who is just pretending to be a submarine.
