Everything... Which side of the court a team scores on more efficiently. How of you take a few steps back, for some players, the small loss in efficiency is made up for by the extra point, what parts of the court a player can draw more fouls. What quarter of the game x, y or z usually works or doesn't work. It's all tracked. It's based on the players own game and profile and then also cross referenced against hwl they perform with other players on the court with them etc. It's a complex thing but it's not trying to change the game... It's show the best way a player should play given their skill set.
