The winnnnn-er, with a near-perrrrfect score of 12/13 is...................... D_Katana.
The runner-up, with 9/13 is Kassy, and close behind with 7/13 is Ben.
I hope the Competition didn't give anyone a migraine. But all competitors put in a grand effort and are eligible for the Book Prize.
The PDF file of the results can be viewed [here].
Alternative interpretations and other comments are welcome.
Finally, a Big Thanks to the Internet Subjects who over the years have taken the test online and have gone to the trouble to submit their personal info and Comments. Without these Comments, much of the subtlety in the test results would have remained beyond our grasp, and indeed this Competition would not have been possible.
