In new street additions, Sukasari built increasingly disconnected streets over time, while Qin built increasingly connected streets from 1975 through 1976-1990, then shifted to more disconnected patterns and Zamania fluctuated in its street-construction patterns. For the full network, Sukasari became progressively more disconnected, while Qin became more connected from 1975 through 1976-1990, then grew more sprawly from 1976-1990 onwards and Zamania fluctuated in connectivity. Notably, Sukasari had a more connected network than Zamania in 1975 but the two have since reversed their relative ranking.
