Once everyone is ready, the process starts back up again. The ballots are fed through a human assembly line of different stations. The diagram showing their movement is printed on a big banner and hung on one wall. The hall has a perfectly good projector, which could show the diagram just fine, but a lot less can go wrong with a banner.
First, the ballots are checked, and spoiled ballots are removed, set aside, and counted separately. From then on, each of the non-spoiled ballots makes its way around the room in a slow snake. There are 23 candidates — one dropped out — but they are not, luckily, all vying for the same position. 12 of them are angling for the 3 open council seats, and the remaining 11 are competing for 3 different positions.
Each possible head-to-head race for each position is considered, and counted twice by separate stations. This means that there are 430 separate counting stations counting different aspects of the ballots. Each one is staffed with a number of volunteers, who rotate in and out to take their breaks or to reinforce any part of the line where there is a pile up. They sign into and out of the stations, so that there's a record of who was where at what time.
This is the tedious part. Even with 213,0000 volunteers working across the city (about one in every 400 people is volunteering in some way), counting 10,5343,2245 ballots takes a long time.
