Possession & Shot Share
5 stats
- CF%Corsi For Percentage
- Share of all 5v5 shot attempts (goals + shots on goal + missed shots + blocked shots) while on ice. Above 50% means your team is generating more attempts than it allows. The most common possession proxy in hockey analytics.
- Related:FF%SCF%
- FF%Fenwick For Percentage
- Like Corsi, but excludes blocked shots. Some analysts prefer Fenwick because blocked shots may reflect the blocking team's strategy rather than the shooting team's skill.
- Related:CF%SCF%
- SCF%Score-Adjusted Corsi For Percentage
- Corsi adjusted for game score. Teams trailing take more shots (desperation) while leading teams sit back. Score-adjusting removes this bias to give a truer picture of possession quality.
- Related:CF%FF%
- HDCF%High-Danger Chance For Percentage
- Share of high-danger scoring chances (shots from the slot and crease area) at 5v5. A team with high HDCF% is consistently generating quality looks from dangerous areas.
- Related:CF%xG
- CF% RelRelative Corsi For Percentage
- A player's on-ice CF% minus their team's season CF%. Positive means the team controls play better when this player is on the ice. Isolates individual impact from team quality.

Shooting & Scoring
11 stats
- xGExpected Goals
- A model-based estimate of how many goals a set of shots should produce, based on shot distance, angle, type, and game situation. Compares actual scoring to what's statistically expected.
- Related:G-xGGSAx
- xGFExpected Goals For
- Total expected goals generated by a team or player's shots. Higher xGF means more quality chances created.
- Related:xGxGA
- xGAExpected Goals Against
- Total expected goals from shots faced. For teams, lower is better (fewer quality chances allowed). For goalies, this is the baseline they're measured against.
- Related:xGxGFGSAx
- G-xGGoals Above Expected
- Actual goals scored minus expected goals. Positive means a player is finishing above expected — could indicate elite skill or unsustainable luck. Large values often regress over time.
- Related:xGSH%
- iCF/60Individual Corsi For per 60 Minutes
- A player's own shot attempts (all types) per 60 minutes of ice time at 5v5. Measures individual shot volume independent of teammates.
- Related:CF%
- SH%Shooting Percentage
- Goals divided by shots on goal. League average is roughly 8-9%. Extremely high or low values tend to regress toward the mean over time.
- Related:PDOG-xG
- A1Primary Assists
- First assists on goals — the last pass before the goal scorer. More predictive of future production than secondary assists, which are often coincidental.
- Related:1stP
- 1stPPrimary Points
- Goals plus primary assists. Filters out secondary assists to focus on the points most likely driven by individual skill rather than being on the ice at the right time.
- Related:A1
- P/60Points per 60 Minutes
- Points scored per 60 minutes of ice time. Normalizes production by ice time so players with different roles and TOI can be compared on an even footing.
- Related:G/60xG/60
Goaltending
4 stats
- SV%Save Percentage
- Saves divided by shots faced. The most basic goaltending metric. Doesn't account for shot quality — a goalie facing hard shots from the slot looks worse than one facing perimeter shots.
- Related:GSAxHDSV%GAA
- GSAxGoals Saved Above Expected
- Expected goals against minus actual goals against. Positive means the goalie stopped more than the model expected — the gold standard for modern goalie evaluation. Accounts for shot quality unlike raw SV%.

Special Teams
3 stats
- PP%Power Play Percentage
- Goals scored per power play opportunity. PWHL average is roughly 15-17%. A strong PP forces opponents to play disciplined, creating a deterrent effect beyond the raw conversion rate.
- Related:PK%
- PK%Penalty Kill Percentage
- Percentage of opponent power plays killed without allowing a goal. The inverse of the opponent's PP%. A weak PK compounds undisciplined play — penalties become doubly costly.
- Related:PP%
- FO%Faceoff Win Percentage
- Percentage of faceoffs won. Gives initial puck possession after stoppages. More important in the offensive and defensive zones than at center ice.
Advanced / Impact
3 stats
- RAPMRegularized Adjusted Plus-Minus
- A regression model that isolates each player's impact on expected goals, controlling for teammates, opponents, and ice time. The most rigorous single-number player impact metric. Positive = helps the team, negative = hurts.
- Related:xGCF%
- TOITime on Ice
- Total ice time. Coaches deploy their best players more — high TOI usually signals trust. TOI/GP (per game) is the standard format.
- +/-Plus/Minus
- Goals scored minus goals allowed while on ice at even strength. A traditional but deeply flawed metric — heavily influenced by teammates, opponents, and goaltending. Use RAPM or on-ice CF% for a better picture.
