It's worhtless to ask about feedback aout this issue if you do not give
information about what the units are along the left-hand scale....?!?!
Degrees? Rads? Quaternion-units?... It's not the first time that people try
to "explain" the jumps between the least-representable-units of a piece of
hardware/software....:-)
