A method of tracking mail pieces includes determining that an observation event has not occurred with respect to a high value mail piece. The annotation engines automatically classify the type of annotations, including, but not limited to: a highlight annotation; a blob annotation ; an underline annotation; a vertical bracket annotation; a call-out annotation; and a free-note annotation. A display control unit displays the composite image on a monitor. A first chance mechanism controls the movement of the antagonist element along the center sections.
