From: The interplay between pitch control and top speed in soccer considering the stamina factor

Team average speed-dependent pitch control variation \(\langle \Delta PC_v\rangle\) vs the stamina factor \(\xi\), for each role of a player. For each \(\xi\) and pair team/game, we only modify the top speed of the players with the given role. Then, we estimate the variation of the pitch control, \(\Delta PC_v\), and normalize it by the number of players per modified position in that team and game. Lastly, we average the variations over all games played by a team for each role considered: defenders (circles), midfielders (triangles) and forwards (squares).
