What is Effective Ownership (EO)?

Effective ownership (EO) is how much of the field gains points when a player scores, including the captain multiplier.

Own a player and you count once. Captain them and you count twice, because a captain's score is doubled. A player selected by 40% of managers and captained by 20% has an EO of 60%. Teams Selected By (TSB) only counts how many squads own the player.
