Enhanced Stats Defined
• 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 Statistics
• Shooting Percentages
• Shooting Stats per TOI
• Scoring Stats
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.
• #### Shot Attempts For (SAT For)

• Calculation = (5 on 5): Team shots on goal + team missed shots + opponent blocked shots (excluding empty net). Also called Corsi for
• #### Shot Attempts Against (SAT Against)

• Calculation = (5 on 5): opponent shots on goal + opponent missed shots + team blocked shots (excluding empty net). Also called Corsi against
• #### Unblocked Shot Attempts For (USAT For)

• Calculation = (5 on 5): (5 on 5): team shots on goal + team missed shots (excluding empty net). Also called Fenwick for

Shot attempts and unblocked shot attempts can be expressed as a percentage, which is helpful to digest larger sample sizes and provide a recognizable scale for comparisons.
• #### Shot Attempts % (SAT %)

• Calculation = 100 x (shot attempts for / shot attempts for + shot attempts against) or 100 x (SATF / SATF + SATA). Also called Corsi for%.
• #### Unblocked shot attempts % (USAT %)

• 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 (SAT% 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.
• #### Shot Attempts/60 (SAT/20)

• Calculation = (Shot attempts for / 60 TOI in minutes) – (shot attempts against / 60 TOI in minutes). Also called Corsi/60
• #### Shot Attempts For/60 (SATF/20)

• Calculation = (shot attempts For x 60 ) / TOI in minutes. Also called Corsi for/60
• #### Unblocked Shot Attempts For/60 (USATF/60)

• Calculation = unblocked shot attempts for (USATF) x 60 / TOI in minutes. Also called Fenwick for/60
Scoring can also be expressed as rate stats by minutes of ice time. Primary and secondary assists are broken out separately, along with two new stats: zone start percentage and SPSV%.
• #### Zone Start % (ZS%)

• 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 Save % (SPSv%)

• 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
Enhanced Stats & Making The Playoffs
For the past several seasons, full-season team shot attempts % close has been a significant indicator of which teams make the Stanley Cup Playoffs.
