Old KH vs New KH Q factor

I am sure that you are right that people sometimes use the term in this
way. However, this "sloppy" definition is not a useful measurement of
anything. Imagine an extra long square taper with a straight crank
parallel to the plane of the wheel. The pedalling force would be
applied further from the wheel - in much the same way as if the taper
were a normal length, and the crank angled out.

I imagine that the critical thing from a unicycling handling point of
view is the ratio of the radius of the wheel to the distance from the
central plane of the wheel to the parallel plane along which the centre
of the pedal moves.
