It provides us with an upper bound in Scandinavian countries with populations that behave like Swedes. How does that generalize to other countries with different densities, distancing compliance, healthcare, etc? Another way to read this is that Sweden is quite a lot worse than it's neighbors, but people there still followed the rules so it's actually a lower bound?
