This was probably pretty easy for them. Apparently they have two people watching the movie, and they discuss it afterwards. They also watch it in "cinema-like" conditions, which I guess means they also have a projectionist.
The price is probably worked out assuming that there are going to be a lot of controversial films, that need long reports, management sign off, discussion with the film-maker over what needs to be cut to get a rating and the potential for appeals.
None of this really applies here.
