Self centering of the graphite requires a gradient in force upon departure
from center.  The gradient need not be equal in all directions as long as it
provides direction toward center and equilibrium at center.   Any
imperfection in dimension or purity moving across a gradient or differing
gradients would result in a change of force and have an affect on smooth
motion.  Using pencil lead in particular brings to mind the inclusion of
clay for hardness control which could greatly affect operation.  If I
understand the two float pontoon configuration I would expect any
differential notching to also result in a turning which could be detected by
comparing movement of parallel edges.  Known insertion of non uniform
graphite could then be measured.
