For the full network, Chauhaddi became more connected from 1975 through 1991-2005, then grew more sprawly from 1991-2005 onwards, while Jalali fluctuated in connectivity and Godagari became progressively more disconnected. Notably, Chauhaddi had a more sprawly network than Godagari in 1975 but the two have since reversed their relative ranking.
