But the math result of 170 and -170 would be zero, since -170 + 170 = 0.
If zero is north, and 170 and -170 are just east and west of south, the
average of the two readings would be north, instead of south.

I think in the end, one just has to figure out what the end result of the
data has to be and tailor the system to fit.

Remember, this sort of thing is why creative problem solvers with a good
grip on the underlying concepts will have jobs for a good long time to come.
So be grateful these problems exist!
