## Equation

In hockey, Corsi is an advanced hockey statistic thatĀ calculates as follows:
Corsi = (Shorts on Target For + Missed Shots + Blocked Shots Against) – (Shots on Target Against + Missed Shots Against + Blocked Shots For)
All stats are taken from even strength, 5 on 5 play.
Relative Corsi is a calculated as:
Player Corsi – Team Corsi

## Example

If a team has the following stats:
For – Shots: 1,091 – Missed Shots: 417 – Blocked Shots: 182
Against – Shots: 918 – Missed Shots: 422 – Blocked Shots: 111
Their Corsi would be calculated as:
Team Corsi = (1,091 + 417 + 111) – (918 + 422 + 182)
Team Corsi = 1619 – 1522
Team Corsi = 97
This team’s Corsi would be 97.
If a player’s team recorded the following stats while they are on the ice:
For – Shots: 120 – Missed Shots: 47 – Blocked Shots: 22
Against – Shots: 140 – Missed Shots: 42 – Blocked Shots: 12
Their Player Corsi would calculate as:
Corsi = (120 + 47 + 12) – (140 + 42 + 22)
Corsi = 179 – 204
Corsi = -25
This player’s Corsi would be -25
The player’s relative Corsi would calculate as:
Relative Corsi = (-25) – 97
Relative Corsi = -122
This player’s relative Corsi would be -122

## What is Corsi?

Cosri is an advanced statistic used in hockey that compares the total number of offensive and defensive “actions.”

## What counts as a “Shot for” or “Shot against”?

In hockey, a “shot for” is a shot attempt that is either stopped by the goaltender or goes in the net.
A “shot against” is the opposite.

## What counts as a “Missed shot for” or “Missed shot against”?

A “missed shot” is when a team shoots the puck towards the net, and it does not go in the net and is not stopped by the goaltender. A shot that is made and hits the net post or crossbar (and does not go in the net) is considered a “missed shot.”

## What is “Blocked shot for” and “Blocked shot against”?

A “blocked shot for” is recorded when a team’s player that is not the goalie blocks a shot that was made against their net (in their defensive zone).
A “blocked shot against” is recorded when a player makes a shot towards the other team’s net and the shot is blocked (by a player who is not the other team’s goalie).
It should be noted that a “blocked shot for” is a defensive action, while a “blocked shot against” is an offensive action.
