Enthusiasm for NTs drop slower than the usual standard. The same goes for its progression. As you've underlined, there is only one game per week, so the BBs have established that enthusiasm should drop or up slower that what we experienced in our respective franchise.
As for the stages, it depends on the type of competition.
For example, in continental tournaments, the 4 top teams are places in two groups with results not carrying forward. Than the 2 top teams advance to the semis with the 1st competing against the 2nd of the other group. The two finalists qualifies for the World Championship.
& congratulation for your magnificent victory höfðingi. You should try to save some enthusiasm for the second stage of the competition if you're sure to qualify! Of course ;-).
