I like simple processes, Occam's razor if you will. I simply pull the lens stage out to rough focus, work out the Shimmyflugey thingy (aim the lens stage at the ground in line with the back) then do fine focus. Simple! I think most people that use view cameras overcomplicate the hell out of it. I am happy for you if you can twist your camera into a pretzel but you never need to in the real world. Maybe in brochures....
