Discrepancies: polling stations with 1.2 million registered voters (online voting in Moscow and N.Novgorod, 7 regions in total). For the first time GAS-Vybory was incorrect: the official total data did not match the sum of data for PECs, i.e. for individual regions, the data from parsing was more correct than the official CEC data.
Digital PECs were not included in Shpilkin's parsings in 2020.
The CEC, by introducing a captcha mechanism on its website, deliberately created obstacles to citizens reading and analysing election results. This, in turn, reduced the reliability of capturing published data using the Wayback Machine and similar servers.
