Just so you know, a automatic machine recount required by law DOES include reprocessing all of the ballots through the machine.  If a manual recount is ordered, then ballots are reviewed manually by teams and piles are made...one pile for each candidate and the ballots are place accordingly into the appropriate pile.  Then the total number of ballots for each candidate are counted.  For more information on how it really works, read the Florida Statute FS 102.166 https://www.flsenate.gov/Laws/Statutes/2018/102.166  or the Recount Procedures Rule 1S-2031 https://www.flrules.org/gateway/RuleNo.asp?ID=1S-2.031
