They show the 2019 one year ranking and then below it shows the 3 year rolling average. Click on the team and it will show you how many points they earned for each tournament. You can tell I spend way too much time with this stuff. Many teams will display their "rankings badge" on the team website. The more top tourneys you play the more opportunity for points.Interesting 3 year rolling average.

Perhaps can see coaches consistancy better. Since rosters can vary yearly.
