For the full network, Yeysk grew more disconnected from 1975 through 1991-2005, then improved, while Laishui became progressively more disconnected and Pakribarawan became progressively more disconnected. Notably, Yeysk had a more sprawly network than Laishui in 1975 but the two have since reversed their relative ranking.
