And so many special rules. Observers are constantly thrown out or denied rights, because even the local officials running the show don't know the rules. Because, in the end, it is not that simple. Berlin right now has an issue that they forgot to specify which of multiple valid method are used to calculate the excess mandates.

It is never as simple as just some paper ballots. But we have a bigger problem. It's a problem at scale. We have all those issues because we do not have enough experts to run all the voting locations at once. The observers need to understand the rules and their rights. The official needs to do so, too. The work of an expert is not scalable, because he cannot be at all places at once.

However, an expert who audits the software is very scalable. One expert can find issues everywhere.
