Mochán's analyses are about the PREP numbers. The PREP totals are ignored when the official count begins, and do not have any legal validity for the purposes of deciding the election. On the other hand, the existence of overvotes and of undervotes is one of the grounds for requesting that an electoral packet be opened and recounted. Mochán notes that the official totals does not include the information on leftover blank ballots, so that a verification of undervotes and overvotes in the case of adding up errors is impossible.
