Sorry, but is this really the determining factor? There may be some crappy exhibits with 6-8 Penguins that would win by this criteria!
No, it's just we were discussing the relative space each penguin had, and then it got more complicated and I thought this was the fairest way to evaluate the relative sizes of the exhibits. Of course it is way off course and almost entirely a wild tangent, but debate takes you places you have never been before after all...
