If official election results processed by an electronic tabulation system, at which level results are entered into an electronic tabulation system?

OAS EOM Mission, Ecuador General Elections 2021, Preliminary Report, accessed 9 February 2021

“The Mission recognizes the substantial improvements in the CNE computer systems as well as the steps taken to increase the channels for disseminating information on election results. […] In addition, the report states that, following a computer system verification in which the scanned images of the tally sheets were compared with the values entered into the system, 10 tally sheets were found to require correction, as they had been recorded as zero tally sheets. In other words, with the approval of that report, the CNE proceeded to correct a total of 18 tally sheets.”

Upon completing their initial scrutiny, polling station officials send their results in paper form to a local Precinct for Transmission and Publication of Certificates.
