Most recently, Amarshi's incremental SNDi rose from 6.36 to 7.23 between 1991-2005 and 2006-2020.

In new street additions, Amarshi built increasingly connected streets from 1975 through 1976-1990, then shifted to more disconnected patterns, while Córdoba built increasingly disconnected streets over time and Donostia / San Sebastián fluctuated in its street-construction patterns. Looking at the full network, Córdoba and Donostia / San Sebastián both became progressively more disconnected, while Amarshi became more connected from 1975 through 1991-2005, then grew more sprawly from 1991-2005 onwards. Amarshi and Córdoba have been converging in their street-network character since 1975.
