This app calculates a goals for and against average using the formula goals for ÷ (goals for + goals against). Enter a "Goals For" value and a "Goals Against" value. The Result will give a 3 decimal percentage point number. This average calculation is frequently used in round robin tournament play for several different sports, where a tie may emerge between teams with equal wins. Goals for and against is then used to determine which team or teams have the higher average and will advance after round robin play. This app could be used and stated in tournament rules by tournament organizers. Coaches, parents and players could also use the app to confirm, or project goals required to advance even before round robin play has completed. This standard app calculation should solve any discrepancies may arise when calculating the goals for/against averages. Enjoy the app..
