s only count for two points. Its goal is to show what field goal percentage a two-point shooter would have to shoot at to match the output of a player who also shoots three-pointers. It is calculated by: eFG\% = \frac where: *FG = field goals made *3P = 3-point field goals made *FGA = field goal attempts A common criticism of this formula is that shooters with very high percentage success rates, which favor 3 point shots, would arrive at an eFG% above 100%. It can also be calculated by: eFG\% = \frac where: *PPG = points per game *FT = free throws made *FGA = field goal attempts The advantage of this second formula is that it highlights the aforementioned logic behind the statistic, where it is pretended that a player only shot two-point shots (hence the division of non-free-throw points by 2). An additional formula that seems to be more in use by the statistics actually displayed on websites (but less cited by said websites) is: eFG\% = \frac where: *2FG = 2-point field goals made *3FG = 3-point field goals made *FGA = field goal attempts All three equations yield the same result.
