I was curious which problems you need to solve consistently to maintain a rating. After observing a few contests, I ended up with the following list:

Here X & Y means if you solve from start to X you will usually lose points and if you solve start to Y you will usually gain a few points. This list is just intended as a rough approximation that ignores individual contest difficulty, ranking, international master/grandmasters etc.

That said, am I close in my evaluation?
