In a movable object system ( 10 ) that makes use of both a maintained count ( 31 ) that corresponds to movement of a given object and passpoint events ( 32 ) as generated by a corresponding passpoint signal generator ( 15 ), count zones ( 34, 37, 36 A, 36 B) can be defined for at least one of the passpoint events. Such count zones can be used to aid in determining when significant recalibration of the passpoint event/count value relationships should be undertaken. In a preferred embodiment, such count zones include no more than a single passpoint event.
