What intrigues me is why anyone would do the stated experiment (which is laughable from a design standpoint) and then why someone else would do "analysis" of the "results". Well, it doesn't really intrigue or surprise me...people want attention and being controversial and backing it up with pixel peeping and charts will always garner some attention.
If I shoot 100 shots in a day and get one "good one" I call that a good day. Then again I'm looking for something different, and maybe I have a different metric for what "good" is. Today I shot about 50 images of a black coffee cup. I never really got it "right" or "good", but I got some things that were interesting.
