It's been a while since I read the article, but I would assume that you are presented with a new set of pictures after an incorrect guess. With a large enough DB to avoid repeats I think your averages are way, way off.

  • Titles consisting of a single word are discouraged, and in most cases are disallowed outright.
  • Read Where should I post X? if you're not absolutely sure you're posting in the right place.
