In a movable object system (10) that makes use of both a maintained count (3 1) 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, 36A, 36B ) can be defined for at least one of the passpoint events. Such count zones can be used to ai d 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. |
