Allow moderators to reset a problems counters after problem fixes. problem 457 didn't have the solution marked as correct. So it stayed at 3000. It also had a shorter valid solution. Would be interesting to see what the rating would be after a reset with the correct solution marked since it still is a difficult problem.

yeah, that could be a good option.

hopefully in time a problem will be averaged out anyway on difficulty.

Recently a lot of problems by one person have been submitted that haven't had a solution marked or that had another conflicting path that caused the problem to not recognize a solution. So these problems are rated 3000 or near 3000.

Unfortunately if you try for the hardest problems you repeatedly get Gokul's problems many of which didn't have a valid solution path when most of the solvers first tried them. So many are still near 3000. It rather defeats the idea of getting the hardest problems.
Allowing later attempts to influence the rating would be an alternative to a reset of the count.
I'm open to suggestions.
Gokul has been posting new problems faster than I can fix them. Some are quite interesting once they have a valid solution and are fixed.

For problems that a lot of people tried, it will take a long time to compensate for 0% right out of say over 60 persons. That is most of our registered problem solvers.
He has got better at having at least one solution marked right which helps a lot.

The more recent attempts should change have a larger affect on the rating than just affecting it by a ratio of 1/number of tries. This is especially important in case a problem changes or a solution path is corrected, etc. Something like CalculateDifficultyUsingTriesOverPastWeek()*.65 + CalculateTotalDifficulty()*.35 Should do the trick.
