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

• +198

 » 6 days ago, # |   +79 Imagine tourist being unable to solve a 2100 problem...Rating system gets a "WA on test case 1610" verdict
•  » » 6 days ago, # ^ | ← Rev. 2 →   +28 I think that if *2100 problems are in such difficulty like this, I will never become a master.UPD : It was updated.
 » 6 days ago, # |   +32 Maybe because there were blues among these 6 people...
•  » » 6 days ago, # ^ |   +24 But only 6 people have passed it in the contest
•  » » » 6 days ago, # ^ |   0 Maybe Mike just calculates average rating of these people
•  » » » » 6 days ago, # ^ |   0 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
•  » » » » 6 days ago, # ^ |   +49 That should be $\frac{3366+3315+2838+1772+1714+2236}{6}\approx 2540$. So the problem should at least get *2500.
•  » » » » » 6 days ago, # ^ |   0 Calculates average performance and not rating?
•  » » » » » » 6 days ago, # ^ | ← Rev. 2 →   0 So calculating average rating is a type of wrong logic.Even so, the rating I calculated(*2500) is higher than the actual rating(*2100).
•  » » 6 days ago, # ^ |   0 I don't think so -- a newbie ACed 1610I and the problem got a normal 3300 rating
•  » » » 6 days ago, # ^ |   0 he_____hezhou may be hehezhou 's account.
•  » » » » 6 days ago, # ^ |   +4 likely, but then the system shouldn't be able to tell...
 » 6 days ago, # |   +21 Also 1603F - October 18, 2017 is *2700 but only 3 people solved the problem officially
•  » » 6 days ago, # ^ |   +3 fun fact: djq_cpp said 1603F - October 18, 2017 is a classical and trivival problem.
 » 5 days ago, # |   +36 I'm curious about the way to calculate the difficulty of problems... I don't think that it's reasonable.
 » 5 days ago, # |   +49 It is now fixed. It is now 3100. Funny that the difference is a whole 1000 in rating.
 » 5 days ago, # |   +72 MikeMirzayanov do you type the ratings in manually?
