By LYC_music, history, 3 years ago, In English

I can't understand it. Only 6 people have passed it in the contest.

Imagine tourist being unable to solve a 2100 problem...

Rating system gets a "WA on test case 1610" verdict

    I think that if *2100 problems are in such difficulty like this, I will never become a master.

    UPD : It was updated.

Maybe because there were blues among these 6 people...

      Maybe Mike just calculates average rating of these people

        IMO it would be faulty logic -- if tourist makes an alt, and becomes the only one to solve the problem, that shouldn't make the problem get a 800 rating. Mike wouldn't have calculated it this way

        That should be $$$\frac{3366+3315+2838+1772+1714+2236}{6}\approx 2540$$$. So the problem should at least get *2500.

          Calculates average performance and not rating?

            So calculating average rating is a type of wrong logic.

            Even so, the rating I calculated(*2500) is higher than the actual rating(*2100).

    I don't think so -- a newbie ACed 1610I and the problem got a normal 3300 rating

Also 1603F - October 18, 2017 is *2700 but only 3 people solved the problem officially

I'm curious about the way to calculate the difficulty of problems... I don't think that it's reasonable.

It is now fixed. It is now 3100. Funny that the difference is a whole 1000 in rating.

MikeMirzayanov do you type the ratings in manually?
