The procedure to determine a keeper’s proficiency involves a simple calculation. It is found by dividing the total number of goals conceded by the number of games played. The resulting value represents the mean number of goals allowed per game. For instance, if a netminder lets in 25 goals over 50 appearances, the calculation 25 divided by 50 yields a value of 0.5. This result signifies that, on average, the individual conceded half a goal in each game played.
This metric serves as a quick indication of a goaltender’s performance and consistency in preventing the opposing team from scoring. Its use provides a standardized way to compare individuals across different leagues and eras, although a direct comparison can be misleading without considering factors such as team defensive strength and league scoring trends. Historically, this simple measure allowed for basic comparisons before more advanced statistical analyses became readily available.
