They didn’t hand count them. They run them through counters again. Where do you get this idea that they hand count ballots?
You have got to be kidding me if you think 4,000,000 ballots can be counted by hand in a day.
Do an internet search on “Georgia hand recount 2020,” dude. They counted them by hand. It took about two weeks.
That was pretty much the end of the hand recounts because by that time everyone in the Trump campaign knew that THE COMPUTERS WERE NOT THE ISSUE.
