While Lake Ronkonkoma and Toboali both built increasingly disconnected streets over time, Xiaoguan built increasingly disconnected streets from 1975 through 1991-2005, then improved in new street additions. Looking at the full network, Lake Ronkonkoma and Toboali both became progressively more disconnected, while Xiaoguan grew more disconnected from 1975 through 1991-2005, then improved. Notably, Xiaoguan had a more sprawly network than Toboali in 1975 but the two have since reversed their relative ranking.
