HP is "impeccable"

Today I came across a research report for ink quality. The report was ordered by HP and its goal was to "prove" HP inks are better than any other inks. The research showed HP inks are the best of all. As they say, "he who pays calls the tune". Here are some graphs with the results. In the second one I admired the 0,0%...Even statistically this result is not possible. The researchers go against the stats :)





Here is the full report available for download.
