Could be 5 stars.
The app could be five stars if it had on demand viewing of the events. That could be too much for the app, I’m not a developer. But it would be nice to be able to go back and watch some of these events when we are not able to see them due to having to be at work or family gathering. Knowing the score is one thing but being able to go back and see how someone obtained the score is what makes for watching.
