For the first time, enhanced statistics are now available on NHL.com. “Enhanced statistics” are statistics derived from the NHL’s real-time scoring feed with clearly defined formulas. Shot attempts (SAT), also known as Corsi, and unblocked shot attempts (USAT), also known as Fenwick, are two enhanced stats that are commonly used as a proxy for puck possession. The variations of these enhanced statistics give insights into analysis of time on ice, relative performance and in-game context. Also displayed for the first time, are other enhanced stats such as primary and secondary assists (1st A, 2nd A), rate stats like goals/20 (G/20) and zone starts (ZS%).
Shooting Stats per TOI
Shot attempts (SAT) and unblocked shot attempts (USAT) are used to measure puck possession for a player or team. When a shot is attempted during 5-on-5 play, all of the skaters on the ice for the team that attempted the shot receive a +1 in shot attempts (SAT) and the players on the opposing team receive a -1. If the attempt is not blocked, the players on the shooting team also receive a +1 in unblocked shot attempts (USAT) and the players on the opposing team receive a -1.
Calculation = 100 x (shot attempts for / shot attempts for + shot attempts against) or 100 x (SATF / SATF + SATA). Also called Corsi for%.
Calculation = 100 x (unblocked shot attempts for / unblocked shot attempts for + unblocked shot attempts against) or 100 x (USATF / USATF + USATA). Also called Fenwick for%.
Shot Attempts % Close
Calculation = shot attempts % (SAT%) when team is within one goal of their opponent in periods 1 and 2, or tied in period 3. Also called Corsi for% close
Shot attempts and unblocked shot attempts can be expressed at a rate per 60 minutes of ice time. This helps even the playing field when it comes to analyzing players who receive different amounts of ice time.
Zone Start percentage is the ratio of how many faceoffs a player is on the ice for in the offensive zone relative to the total offensive plus defensive zone faceoffs he is on the ice for. Neutral zone faceoffs are ignored. Players with a higher zone start percentage tend to have more opportunities to generate shot attempts.
Shooting % Plus
SPSv% is 5-on-5 on-ice shooting percentage plus 5-on-5 on-ice save percentage. It is usually expressed out of 1000 and it trends toward 1000 over the long term. Very broadly, SPSv% can indicate "puck luck"; players with SPSv% well below or above 1000 can be expected to get more (or fewer) bounces in the future. Also called PDO
