In summary, the 2011 Intl Math Olympics had a Windmill problem that stumped many young participants. Only one participant received a perfect score out of 26. The video provided on AoPS offers insights and data from a human factors study that may help in comparing difficulty levels.
It is a nice video.

The Intl Math Olympics of 2011 had a problem that stumped many young participants except one who received a perfect score:
Several participants received a perfect score in that problem (the video has the number somewhere, 26 or so). Only one received a perfect score in all six problems.
26 is still a very low number, especially for problem 2 (which is usually easier than problems 3 and 6).

Instructive video for teachers and students on problem solving. Data from human factors study, called social in the video, might help resolve the difficulty level comparison issue.

How many or which participants were coached or prepared with a similar problem?
