Hmmm....let's see: Trevor wants us to check that the magnetic bearing
(in the range 0 - 359 degrees) is smaller than the true bearing (0-359 deg)
plus 360 degrees (i.e 360-719 degrees).
If I understand his recipe correctly (probably not!) that means magnetic
is always numerically larger than the true.
Now that's a novel assertion!
