For many, pretests are a feature of Codeforces.

However, we are now having fewer FSTs and it seems to everyone that "I should pass the main test when I pass the pretests".

If so, what's the aim of having pretests? Why not just test main test during the contest?

Some participants say that the stress of judging server is quite high during the contest. In many cases, the number of main test is no more than 5 times the number of pretests, while reducing the constraints to 1/5 will have the same effect.

Just take Codeforces rounds long ago for example, there are much more FSTs.

I also have some FSTs, too. But for me it's just the fascinating part of CP. CP should be something that has some randomness.

Please, raise the FST rate for a little bit (just a little bit will be good, like the contests long ago)!
