Seems like there are 4 pages of unjudged submissions ...
If two or three problems in div1 round have near the same difficulty and the next problem is much more difficult than that 2 or 3, than results are unfair: participants that solved these problems are sorted according to luck, not to their real skill. Examples:
Also hacking is near impossible in div1 rounds because participants are rather clever to make mistakes.
So I think that div1 rounds should be extended with div2 problems or div1 participants should compete with div2 contestants,
What is your opinion on this ideas?
