Boxing is only really needed when visibility and/or ground mean you have to be spot on all the time.
So, I'm pacing a bearing for a kilometre in a white-out on a plateau and meet a rocky outcrop blocking my path. So as not to lose my bearing or pacing, I set the needle on east, pace 50, set it in north, pace 50, set it on west, pace 50, set it on north and resume my main pacing 50 paces on.
For avoiding a large area, it's easier to do normal bearings, just with intermediate points .
I'm walking on Dartmoor in the fog. I can see on the map there is a bog on the direct line between where I am and where I want to go. So I plot a bearing/pacing to something off to one side (perhaps even an imaginary point on the map) then when I'm there plot the leg to my destination. For some instances there could be two intermediate points.
Of course, all this assumes a lack of features that can be used for navigation. If possible I'd choose a route like turn right and follow the ridge to where it flattens into a shelf, walk on a bearing of x until I meet the stream, turn left and walk down the stream to where it gets steep, turn right and I am back on track.
