Some duplicate content better than others?

Google search engine is smart enough to find the right thing out. Sometimes they faced problem to show the result, but after Penguin update I don't believe that duplicate content could be good choice.

Does any one know if the number of times content is used on the web effects how google sees it? For example if you grab a wikipedia article on Elvis it might be on 40,000 other sites. But what if the content is only on two other sites or 8 other sites? Would this content do better?

As for the lower amount of presence and rarity that duplicate content might work. But I think as the new updates of google algorithm it is too risky to test.

now a days it's very easy for google to determine the original and copied content original contents only works after the google panda update...
