My thought was to see how active a player is.
Most of main accounts would have a high setup statistic, that's true.
But there are a lot of other accounts which playing without setup or active racing.
A new player have the change to see more informations about a league and her activity before the change to the league.
And all manager of a league have the chance to see more informations about a new manager.
You can, more or less, see this already by how many races they complete compared to total number of races. It wouldn’t help with activity as some managers set up,and don’t attend the live race so agree with Kevin this would be a pointless addition.
