If that's true (and at this point, just about anything is believable), that's absolutely absurd. The only reason to 'adjudicate' 60% of the votes would be to steal an election, period. I would say eyeballing more 2% maybe 3% of total ballots would be incredibly suspect.
I am hearing adjudication rate in Maricopa county was 11% when normal has been 3% in past elections.
