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