Almost every contest I participate, at the end I say "it was speedforces" and probably most of the experts too. And I thought, why is it the case? So I have a offering, but first I will talk about why I have that offering.
Contests have problem arrangement based on their difficulties. Even if the difficulty of the two adjacent problems were same, amount of people solved first is more than the second one. Thats because of the fact that people have less time every problem they solve. On top of that, the problems hardness increases, so most of the people I know (Including me) gives up when they solve an ok problem. And this makes a pile of people who solved the first x problem but doesn't have time + courage to solve the other problem.
So my offering is because of the fact that the number of people solved problems drops exponentially, making the problem difficulty gap less between C, D and E (maybe even same hardness). So contests may be less speedforces.
