Indeed, if one had a manual tranny and was using the magnets it would be
*vital* to disengage the CC before depressing the clutch... otherwise
the magnets would detect a slight decrease in axle speed and increase
throttle -- then detect no increase in axle and increase throttle more,
etc -- quickly over-revving the engine.

That is the major disadvantage of the magnets with a manual tranny.  In
practice not much of a problem as one is seldom downshifting in an
environment where CC might be used.  When say approaching a stop, simply
braking before de-clutching (the normal thing to do) disengages the CC.
