Yes, it was just at the beginning of the electoral campaign. Several political parties used that document. In some cases people who worked for them used it to do their own calculations. It was rather good, since everyone was working on the same basis and the same calculations. It wasn't necessarily possible to cheat. If the figures deviated somewhat afterwards, it was not our fault. We provided a baseline that everyone could use. I think that is not a bad idea.
