Moral of that story is that 8x10 sheet film rules? Something a lot of us already knew, pits its so... well... huge! Its not a very real life test though.
I still think better tests are ones from comparing actual real life prints (eg 16x20/20x24). There's a reason film is still used by us, nice to know there's some data supporting it and not just a 'look' though I guess.
