I found this interesting. KenPom looked at his ratings and point-spread data on home court advantages. Some takeaways
- Home court advantage on a team-by-team basis is hard to estimate
- Home court advantage has been decreasing across different sports in recent years
- There is not a large difference between the best and worst home-court advantages
- He states "Teams that run up a long home-court winning streak are doing it mostly because they are better than their opponents and they just happened to save their worst performances for either poor opponents at home or games on the road. Sure, the home court contributes to a long winning streak, too, but any special advantage a team has in their building is a very small factor."
