Four workers, two hours, 2-3k ballots per hour per machine per person. 98% big guy.

16k-24k votes would absolutely do it, deboonkers. They don't even need to be switched (double value if "corrected") they could be thrown out and it's over.

Further, the combination of the flash drive and the revelation that machines can be reset for different precincts on the fly (possibly even remotely) means this counting video could have posted updates to any county.
