FIBA Organizer uses an Efficiency Rating stat for basketball. By default it is calculated as follows, but is customisable by League:
(points + assists + blocks + steals + fouls on + rebounds) – (turnovers + blocks received + fouls + tech fouls + (2PA - 2PM) + (3PA - 3PM))
This stat can be activated in FIBA Organizer via Competition Setup > Stats Profile Configuration:
You must ensure that you then activate the correct stats profile for your competitions via Competitions > Comp Details.
The Efficiency Rating stat will appear in the LiveStats webcast box score.
