One of the ways to improve the quality of the solver rating, is to penalize "skipping" problems when solving. Since the quality of problems varies, some allowance must be made for the skipping of low quality problems. But when a solver skips more than 1 in 3 on average, a penalty is justif...

I finally found what is "buggy" in the problem difficulty system. "Difficulty" is lowered drastically when a problem is solved by a relatively "weak" solver. However, the system carries no memory on how weak a player really is. Anyone with a non-pro account may chose to...

See it now! Internet Explorer 8 doesn't pop up the difficulty rating on my computer screen but Firefox does. The chart reveals that incorrect attempts add little value to the difficulty stat but incidental solutions may cause dramatic drops. I suppose this behavior is by design and just happened to ...

I am not sure how to find that graph. Do I need a pro account for that? By now I have a theory on how the problem difficulty rating might plummet suddenly. I may have edited some variations containig "attempt paths" by solvers. When an attempt path changes, possibly the attempt count will ...

It happened a few times to me that, immediately after I edited the solution to a problem, its difficulty rating suddenly plummeted by 60 or 70 points. Of course, this might have been coincidental with many attemptees solving my problem correctly, but that event seems unlikely. Particullarly, since i...
