High-, medium-, and low-danger tiers sort unblocked shot attempts by how likely they are to score.
HDCFHD
Unblocked shot attempts from IceSheet’s high-danger tier while a player is on the ice. It is the most direct danger-weighted possession count.
Calculation
Unblocked attempts for with xG >= 0.20
Note. HDCF% is one of the quickest simple approximations of xGF% when full expected-goal data is unavailable.
HDCAHD
High-danger unblocked attempts allowed while a player is on the ice. Elevated HDCA usually points to defensive-zone breakdowns or poor net-front control.
Calculation
Unblocked attempts against with xG >= 0.20
HDCF%HD
Share of high-danger attempts generated versus allowed. It is one of the strongest simple process indicators available.
Calculation
HDCF / (HDCF + HDCA)
HDSOGHD
High-danger attempts that reach the goalie instead of being blocked or missing the net.
Calculation
High-danger shots on goal, including goals
MDCFMD
Shot attempts from medium-danger areas. It helps fill in the offensive picture outside the slot.
Calculation
Unblocked attempts for with 0.08 <= xG < 0.20
LDCFLD
Shots from the outside. Plenty of these with few high-danger chances usually means the puck is in the zone but nothing is really threatening.
Calculation
Unblocked attempts for with xG < 0.08
REBHD
Shot attempts that occur within a few seconds of a prior shot on goal by the same team. Rebounds are treated as high-danger events.
Calculation
Same-team shot attempts within 3 seconds of a prior shot on goal
Note. Rebound control is one of the clearest teachable goalie skills and a major differentiator in net-front defense.
HDSlot, net-front, rush, and rebounds
The most dangerous plays in hockey, and where most goals come from.
MDInterior lanes outside the slot
Still meaningful offense, but at lower scoring probability than the true slot area.
LDPerimeter, point, and wide angles
These shots can show a team has the puck in the zone, but on their own they rarely threaten the net.
