"Following the November 2022 election, staff re-counted 5,535 ballot cards from randomly selected precincts by hand, then compared the hand-counted vote totals to the software counted totals. These hand-counted ballots came from 13 precincts, with no more than five of the contests on the ballot re-counted in 11 of the precincts.

It took two teams of four people 8 days to hand-count this small sampling of ballots, which comprised just 8 percent of the nearly 69,000 ballots cast by Shasta voters in that election."

Quoting: "Analysis of Manual Tally Options for Shasta County" Page 11]

Required 8% Hand Recount: California Election Code $S 15360
