Also what is the meaning of ratings given to puzzles (ratings and average ratings)?
Each puzzle can be rated on a scale of 1-10 by solvers. The ratings can be done during the test window and is open for some time after the test also.
Average rating is a weighted average of ratings in conjunction with LMI rating of the solver/rater. For example, if a person with LMI rating 800 gives a rating of 6 and a person with LMI rating 400 gives a rating of 10, the average rating will not be 8, it will be closer to 6.
