- Core Metrics
5v5 Corsi For Percentage (CF%): A ratio that shows the percentage of shot attempts created by a team versus the total shot attempts in a game during 5-on-5 situations.
5v5 Score-Adjusted Corsi For Percentage: The above metric but adjusted for score effects. 5v5 Corsi Relative (Corsi Rel): The percentage point difference between a player’s CF% and the team’s CF% with that player on the bench.
5v5 Score-Adjusted Corsi Rel: The above metric but adjusted for score effects. 5v5 Expected Goals For Percentage (xG%): A ratio that shows the percentage of weighted unblocked shots created by a team versus the total weighted unblocked shots in game during 5-on-5 situations.
5v5 Points Per 60 (Points/60): The amount of points averaged by a player per sixty minutes of 5v5 ice time. This metric can also be presented for all other situations (5v4, 4v4, etc).
Individual Expected Goals Created (ixG): The amount of Expected Goals generated by an individual player. This metric can be filtered by situation and can also be presented in “Per 60” form.
5v4 Corsi For Per 60 (CF60): The amount of shots generated by a team during 5-on-4 situations per 60 minutes of play. A good way to evaluate the shot creation efficiency of a power play. This can be presented as a team-metric, or for individual players (how many shots did the team average when an individual was on the ice).
4v5 Corsi Against Per 60 (CA60): The amount of shots allowed by a team during 4-on-5 situations per 60 minutes of play. A good way to evaluate the shot-prevention efficiency of a penalty kill. This can be presented as a team-metric, or for individual players (how many shots did the team allow when an individual was on the ice).
