In new street additions, Patahi fluctuated in its street-construction patterns, while Santai built increasingly connected streets from 1975 through 1976-1990, then shifted to more disconnected patterns and Share built increasingly disconnected streets from 1975 through 1991-2005, then improved. For the full network, Patahi grew more disconnected from 1975 through 1976-1990, then improved, while Santai became more connected from 1975 through 1976-1990, then grew more sprawly from 1976-1990 onwards and Share became progressively more disconnected. Notably, Patahi had a more connected network than Santai in 1975 but the two have since reversed their relative ranking.
