Problem ratings for today's div 3 is out. I don't think that is wise as there is still system testing and hacking is still opened? For example, I hacked someone's C just a while ago and I hacked my old E1's solution(wrote DFS instead of BFS). I think what matters are problems which are not solved quite a lot being hacked such as problem E2 or G and their true rating can jump at least 100 points after system testing in a non impossible scenario.
