Depiction of horizontal lifelines for a hypothetical 100-member Senate for one century. Each horizontal line represents a seat with interspersed green ticks depicting a change-of-seat. The solid green lines depict the years served by individual members who were jointly serving in year 50 (i.e., current hypothetical year). a Hypothetical 100-seat “lanes” with inset showing in-office duration of one member for approximately 20 years; b random vertical distribution of lifelines for current members; c lifelines of current members ordered shortest-to-longest from top-to-bottom according to years already served; d lifeline segments of current members for years served and years remaining decoupled and each ordered shortest-to-longest from top-to-bottom. Note the mirror-image symmetry of the two distributions
