From my experience, the fastest way to work is to start rough and refine later. Move from top to bottom through the controls, and zoom your subject to at least 100%, preferably 200%. First, Start with Standard, then find the Method that suits your scene best : Low, High, Uniform, Highlight. Then adjust Strength, Radius, and Contrast. After that, refine again from top to bottom.
