The marginalization degree of the district was directly related to the time it took for the results to be carried to the corresponding CEDAT. Those of very low marginalization took an average of 4:31 hours; those of low marginalization an average of 6:14 hours; medium marginalization an average of 6:54 hours; high marginalization 8:45 hours; and very high marginalization an average of 10:32 hours. The time it took to get results from a polling place to the corresponding CEDAT was also directly related to the average distance between the polling place and the CEDAT. Almost two thirds of Calderón's votes came from districts with very low marginalization, arriving first, with almost three percentage points advantage over López Obrador. Moreover, it was only on those districts that Calderón obtained victories, while López Obrador was ahead mainly in districts with low, medium, and high marginalization; Madrazo only won in some districts with very high marginalization. Pliego Carrasco states that taking all these factors into consideration completely explains the behavior of the partial tallies, in particular the changes in the rates of growth that began occurring around 9 pm, and the further changes (outlined by the Alianza in their judicial filings) between 2 and 3 am. Pliego Carrasco criticizes Mochán and others for not considering the marginalization and the distance between districts and the corresponding CEDAT, and for considering only a very rough urban/rural sorting of the districts and using methods and techniques that are valid for the natural sciences and engineering but that he considers unjustified in their application to social sciences.
