Several days ago I published a table with first people to reach certain ratings. It featured only ratings above 1500, and adamant advised to do the same, but on achieving ratings below 1500. I found it quite interesting, and, after several days of collecting data about participations of 447911 Codeforces users, I finally made this table. For several reasons I firstly put another table. This is the table of greatest rating rises in the history of Codeforces. The reasons are:

1. I have collected so much data from Codeforces that it would be blasphemy not to use it in as many ways as possible.

2. These tables might intersect a lot: it's easier to get a terrific rise in ratings if you are low-rated. (Many people abuse this and deliberately get very low-rated to make a great jump.)

3. Someone recently posted a table with greatest rating rises and falls. I wasn't able to find this table to check whether it was right, but if someone finds it, you're welcome to put the link in the comments so we can check it.

4. The milestone table is very wide and interferes with Codeforces interface. Putting a long but narrow table above it will fix the problem a little.

So, here it is — the greatest positive rating changes! For technical reasons I always ignore the first rated participation on each account (or else the top-1 rating rise will be xay_naive's first place in Educational Codeforces Round 87 (Rated for Div. 2) gaining 1978 rating points in a single round. This is not a bad participation at all but looking at such participations it is not that interesting).

Now we are ready to see the table with milestones. You can see that worse is truly the tourist of negative ratings!
