They allow votes to be tabulated that come in via Mail In Ballots & Early Voting & they end Early Voting 3 Days before Election Days.
This allows them to dedicate their workforce of tabulators to complete just what comes in on Election Day - which often takes less than 8 hours.
What Florida is doing is called being resourceful. By tabulating Early and Mail-In Ballots before election day, it cancels the bottle necking of votes being tabulated all on Election Day, and it cancels the opportunity for Mail-In Ballots to suddenly swing the election in a different direction at 3am the morning after Election Day.
