I do think the example is bullshit, simply because you could throw ONE very thick pot and have it weight more than 50 pounds. Of course it's a horrible pot and you wouldn't get any better since you only made one piece, but it would get you an A since it would use more clay. Total # of pieces thrown would make more sense than pounds of clay used.
(Not that I think the anecdote is real, but) that's the idea -- the parable was about how the pot with the best quality was found in the 'quantity' team even though this wasn't their objective.
Forgive me if I've missed something but the original comment says the group that threw the most clay scored higher on creativity, not scored higher on pounds of clay thrown.
