Those graphs are charting out the number of votes each batch is won by. There is a clear divide right around the middle of the graph. On the left side, look how much the difference varies. Look at the right side now, there are only two or three different numbers coming out as the difference. Meaning, that somehow in the middle of the night, the vote differences became uniform. So either they all the sudden had the most uniform voting blocks imaginable all being reported after 4 am or the numbers don’t reflect real numbers from ballots and are altered numbers.
