Practical question for my friends.

While I was with Fred learning BTZS, we spent time focusing the view camera in a way in which one simply focused on the near and the far by moving the far standard, found the setting for each in mm on the Canham ruler guide, set the rear standard in the middle of the two, and closed down the lens. Of course, we checked to be sure that everything was in focus by checking the ground glass. One disadvantage of the method was the necessity of measuring two numbers, and the need to removed one's head from under the dark cloth several times in order to accomplish such measuring. Hardly impossible-or even difficult- but some what slow and inconvenient. Now I note that there are all sorts of "fancier" methods in which the far is first focused, and then the near is focused by tilting the lens standard towards the near. Others use all sorts of complex angles and formulas to be sure that the planes of focus are perfect. My question is if the simple method, which seems to work for landscapes, is "enough" or if one really need become involved with some of the more arcane and esoteric features of view camera focusing. Does anyone find that taking the measurements noted above is too incovenient, and that the tilting of the lens standard is easier and quicker because one remains under the dark cloth? I can understand that table top still life photography might need more complex focusing techniques, but for the more mundane and common subjects that I am photographing now....

Thanks for answering what is probably a very basic question for almost all of you.
