http://www.nba.com/statistics/default_regular_season_leaders/LeagueLeadersEFFQuery.html NBA.com has player efficiency ratings, and Steve is ranked number 2 behind Kobe. Efficiency Formula: ((PTS + REB + AST + STL + BLK) - ((FGA - FGM) + (FTA - FTM) + TO)) / G is the formula. That is a pretty good system. Steve is putting up incredible numbers.
