How to calculate game score

Game Score = Points Scored + (0.4 x Field Goals) – (0.7 x Field Goal Attempts) – (0.4 x (Free Throw Attempts – Free Throws)) + (0.7 x Offensive Rebounds) + (0.3 x Defensive Rebounds) + Steals + (0.7 x Assists) + (0.7 x Blocks) – (0.4 x Personal Fouls) – Turnovers

Example

In a game, a player has made: 26 points, 6 field goals, 21 field goal attempts, 14 free throws, 21 free throw attempts, 1 offensive rebound, 4 defensive rebounds, 1 steal, 10 assists, 1 block, 1 personal foul, and 7 turnovers.
Game Score (GmSc) = 26 + (0.4 x 6) – (0.7 x 21) – (0.4 x (21 – 14)) + (0.7 x 1) + (0.3 x 4) + 1 + (0.7 x 10) + (0.7 x 1) – (0.4 x 1) – 7
Game Score (GmSc) = 26 + 2.4 – 14.7 – (0.4 x 7) + 0.7 + 1.2 + 1 + 7 + 0.7 – 0.4 – 7
Game Score (GmSc) = 26 + 2.4 – 14.7 – 2.8 + 0.7 + 1.2 + 1 + 7 + 0.7 – 0.4 – 7
Game Score (GmSc) = 14.1
Therefore, this player has a game score of 14.1.
