Great video and very helpful! The only part I would disagree with after reading much research including Jurach's books on sharpening, would be to use a new stone and never use water or oil for lubrication.
Lubrication retains metal filings creating gouges in the edge of your blade slowly destroying your edge (picture something more like a serrated edge being created with lubrication containing microscopic metal filings) I wrote a short blog article summary if interested @ http://www.mrknives.com/blog/2013/09/24/Knife-Sharpenning-Creating-a-Fine-Edge.aspx
