[Closed] Why is Div. 2 G problem rated 1700 now? It doesn't seem right for me.
By Little_Sheep_Yawn, history, 3 weeks ago, In English

(It seems that the ratings of the problem are already rolled back, so it is no longer a problem for 2248G)

Here it is 2248G. And during the contest, it is something like this:

If it is right, I believe we need to figure out a new way to calculate the rating of a problem, otherwise it only becomes more meaningless.

I remember another problem's rating is much lower than its actual one, due to the fact that the first person to solve it was rainboy.

So maybe we really need a new approach to calculate problems' rating lol.

Maybe it's because of the rainboy effect

    I don't even know how this happens. If I place second in a div1 only losing to a blue/CM I would still get like 3500 perf. Maybe they do something weird like averaging the solver ratings instead of doing something more statistical?

Isn’t it 3000? Did problem ratings get changed because I swear Plus Minus Tree was 2500 because rainboy and kaiboy solved it but now it’s 3000
