Here's a bit of additional info. The ballots contain a long list of offices with multiple choices for most of them. There are thousands of polling places and many hundreds of voting systems or methods. AGT has a limited list of names and only one way to vote.

It should be compared to how we did paper ballots only back before voting machines. The results for many elections were known within minutes of the poll closings. Most of the other results were known by bedtime.
