Thanks for the link, BG. Those guys made a dumb mistake:
From the article, it quotes Hal Koerner:
but I overlooked the elements of being a fast-packer, the time it takes to filter water and stuff. It took longer than I thought
I guess they haven't heard the old news that filtering/treating is not necessary. The "Dip and drink" method saves a lot of time and energy. This bit itself probably added a number of hours to their time!
