Glossary

AdjustedSvPct: Adjusted save percentage; this adjusts for the fact that some teams give up more high-quality shots, while others give up more low-quality shots. This is the weighted-average of SvPctHigh, SvPctMed, and SvPctLow, where the weights correspond to the league-wide percentage of shots from each of those areas. In other words, this is a goalies save percentage if they faced a league average proportion of shots from each of the three shooting zones (high, medium, and low probability of success).

Average Conversion:

Close: Refers to situations when the game is within 1 goal (1st and 2nd periods) or tied (3rd period or overtime)

Color By Statistical Significance: If checked, colors will be adjusted on to a scale of 0 +/- 8. Dark red colors mean that (e.g.) the player's team's shot rate is significantly better than league-average with the player on the ice. Dark blue colors mean that (e.g.) the player's team's shot rate is significantly worse than league-average with that player on the ice.

Use Only Three Blocks: The default Hextally setting divides the rink into 9 areas of the ice (see graphic at bottom of the page). "Use Only Three Blocks" divides the ice into three areas, which correspond to ares where shots have high, medium, and low probabilities of success (shooting percentages).


Save Percentage Zones:
blue = high percentage shots (SvPctHigh)
red = medium percentage shots (SvPctMedium)
yellow = low-percentage shots (SvPctLow)
Save Percentage Zones -- High (blue), Medium (red), and Low (yellow)
