If you go to the standings of May Long Div3, you will see that only two people have solved the last two problems. And everyone who has solved 6 problems are given the rank 3. In this case, all of these people will get performance according to rank 3.

But bro, what's the harm? Well, this completely destroys the purpose of solving 7 problems. By solving an extra problem you will get a rank 2, which won't even matter.

But bro, we cannot give penalty based on time since it's a long challenge right? Well, just sum up the number of participants that share the same score, and instead of giving a rank based on people who have scored strictly more, give rank according to people who have score equal or more (like it's usually done in every standings table).
