So the other day I saw this funny video:
Anyways, that made me wonder, what is the highest drop in rating on codeforce? And after checking thousands of contest results, here's what I found:
| change | contest | user |
|---|---|---|
| -302 | 1081 | wxh010910 |
| -303 | 1696 | popaj |
| -306 | 1552 | cscse |
| -307 | 1033 | vintage_Vlad_Makeev |
| -309 | 1553 | PrincessConsuela |
| -310 | 1615 | pmt2018 |
| -312 | 1654 | Allvik06 |
| -313 | 1654 | csyakuoi |
| -314 | 1450 | Mediocrity |
| -316 | 1523 | yuzhechuan |
| -317 | UtopianZ | 1779 |
| -317 | cfabcdhhhh | 1770 |
| -319 | 1552 | C137 |
| -319 | 1055 | Arterm |
| -322 | 1523 | Roundgod |
| -323 | 1696 | rainboy |
| -325 | 1608 | realFZzzz |
| -327 | 1656 | 300iq |
| -333 | 1704 | dfgzm |
| -334 | 1608 | WeakestTopology |
| -336 | 768 | yosupo |
| -351 | 1615 | delta_X |
| -352 | 1621 | AriaH |
| -356 | 1585 | Wailydest |
| -373 | 1097 | izban |
| -382 | 1774 | Tlatoani |
| -389 | 1148 | kiwikiwi |
| -417 | 1696 | AutumnKite |
As you can see, the biggest drop is -389 rating. While impressive, this is far from optimal, since they didn't get last in the contest. Maybe some blackred can take one for the team and get an even higher score.
Update: someone else got last place and dropped by -417 :O However, they could have dropped more if they were patient and got a higher rating first (smh).
Btw, here are the smallest drops on codeforces. Some of these might be unfair because of the boost you get in your first contests, however with the api there is no easy way to tell.

Probably it should be highest gains instead of smallest drops?
smallest drop is factual.
Oh look! 140870 dropped by -1182 points...
It may be factual but it isn't appropriate.
I love the positivity in the last line!
Please share the link to the cat video. Thanks.
I think there is no video version :(

Unfortunately it changed to a still image on Codeforces

CGR21 refreshed the record.
he actually included two of the rating drops from that contest in the table (rainboy and popaj) but idk how he missed the highest rating drop ever: -417 delta for AutumnKite in that very same contest!
:o
it seems like their submissions got skipped, this probably happened some time after the contest ended
One question : How did you manage to find out those biggest rating changes? Did you manually searched or did you use some sort of automated scripts to find out it.
IDK why is this comment even downvoted, i was just curious to know about how did he scrape the data. It was a geniune question
You're getting downvoted because it's point-blank obvious Aaeria manually searched through every rated contest.
I actually just had my minions check for me

+1009 but first contest
https://codeforces.net/profile/yanzhuozly
+996 but first contest
Who's next?Looking for PinkieRabbit's performance!(maybe in both of two lists)
"Maybe some blackred can take one for the team and get an even higher score."
while not blackred, AutumnKite sure did take one for the team. Didn't expect your wish would be granted so quickly, did you, Aaeria?
CodeForces Global Round 21: Rating Changes
AutumnKite delta: -417 (2871 → 2454)
rainboy delta: -322 (2320 → 1998)
popaj delta: -302 (2330 → 2028)
CodeForces needs to make it easier to upload images, idk how to do this ugh...
I just noticed that you included rainboy and popaj in your table for biggest rating drops, from the CGR21 Codeforces Global Round 21, how did you miss AutumnKite?
now zh0ukangyang has the biggest drop
VivaciousAubergine had -500.
zh0ukangyang had got -3321
