.......I am merely wondering why some people are shocked that they get issues with images that they create using an unrealistic scenario that they have created in order to get the worst results possible from the camera....
Personally I would not expect to be able to get a usable image if i under exposed by 10 stops, but obviously the minority among us believe we should be able to...
Shame on you Canon for releasing a camera that is no use to any normal photographer

Your still missing the point. It is an artificial test designed to highlight a sensor shortcoming. Other manufacturers have figured out how to handle such extreme situations and deliver 1/2 decent results. Canon has had a long history of pattern noise and this test done on some of their earlier releases would lead to stunningly bad results. With this cameras and the 80D Canon seems to have finally caught up with the competition or at least gotten much closer.
