One of the complaints against advanced statistics in hockey is the names of some of the advanced statistics. Sometimes people complain about names like Corsi, Fenwick, PDO, etc. because they don’t have meaningful names. I never really understood it because once you figure it out, which honestly it isn’t that difficult, it isn’t all that difficult. That said, it still seems that some people feel it is a bit of a hurdle for some to get into advanced hockey statistics. I am hoping to revamp and improve my hockey statistics database even more this summer and in the process I wondered if there is interest in having me use some standardized hockey statistics nomenclature that we can all agree on. Here is what I am proposing:

Event Statistics Description
TOI Time on ice
G Goals
A Assists
FirstA First Assists
SOG Shots on goal
SAG Shots at goal (includes missed shots)
ASAG Attempted Shots at Goal (includes missed and blocked shots)
Percentage Statistics
Sh% Shooting percentage (G/SoG)
SAGSh% Shots at goal shooting percentage (G/SaG)
ASAGSh% Attempted Shots at Goal Shooting percentage (G/aSaG)
Sv% Save percentage (G/SoG)
SAGSv% Shots at goal save percentage (G/SaG)
ASAGSv% Attempted Shots at Goal Save percentage (G/aSaG)
ShSv% Shooting percentage + save percentage (Sh% + Sv%)
SAGShSv% Shots at goal shooting percentage + save percentage (SAGSh% + SAGSv%)
ASAGShSv% Attempted Shots at goal shooting percentage + save percentage (ASAGSh% + ASAGSv%)
Other Statistics
IGP Individual Goals Percentage (iG / GF)
IAP Individual Assist Percentage (iA / GF)
IPP Individual Points Percentage (iPts / GF)
ISOGP Individual Shots on Goal Percentage (iSOG / SOGF)
IASAGP Individual Shots at Goal Percentage (iSAG / SAGF)
IASAGP Individual Attempted Shots at Goal Percentage (iASAG / ASAGF)
Zone Starts
OZFO Numer of Offensive Zone Face Offs
NZFO Number of Neutral Zone Face Offs
DZFO Number of Defensive Zone Face Offs
OZFO% Offensive Zone Face Off Percentage – OZFO /(OZFO+NZFO+DZFO)
NZFO% Neutral Zone Face Off Percentage – NZFO /(OZFO+NZFO+DZFO)
DZFO% Defensive Zone Face Off Percentage – DZFO /(OZFO+NZFO+DZFO)
OZBias Offensive Zone Bias – (2*OZFO + NZFO) / (OZFO + NZFO + DZFO)
DZBias Defensive Zone Bias – (2*DZFO + NZFO) / (OZFO + NZFO + DZFO)
OZFOW% Offensive Zone Face Off Winning Percentage
NZFOW% Neutral Zone Face Off Winning Percentage
DZFOW% Defensive Zone Face Off Winning Percentage
FOW% Face off win percentage (all zones)
Prefix
i Individual Stats
TM Average stats of team/line mates weighted by TOI with
Opp Stats of opposing players weighted by TOI against
PctTm Percent of Teams stats the player recorded in games the player played in
Suffix
F Stats for the players team while player is on the ice
A Stats against the players team while player is on the ice
20 or /20 Stats per 20 minutes of ice time
60 or /60 Stats per 60 minutes of ice time
F% Percentage of events that are by the players own team (i.e. for)
D Difference between For and Against statistics

The major changes are instead of calling shots + missed shots fenwick events we call them Shots At Goal (SAG) and instead of calling shots + missed shots + blocked shots corsi events we call them Attempted Shots At Goal (ASAG). Also PDO which is shooting percentage + save percentage is now named ShSv%.

The prefixes and suffixes can be added to individual stats to create new statistics. For example:

  • iSh% = Individual Shooting Percentage (iG / iSOG)
  • TMSAG20 = Team mate average Shots at Goal per 20 minutes of ice time weighted by TOI with
  • OppGF% = Opponent average Goals For Percentage weighted by time on ice against
  • PctTmG = In games that the player played in, the percentage of his teams goals that the player himself scored.

Note that not all combinations of prefixes and suffixes make sense. For example, PctTmSh% or Sh%F but that is self explanatory I think.

What does everyone think? I am perfectly fine sticking with the way I have statistics currently presented but if the majority think something along the lines of the above is better I am all for making the change. If anyone has any other suggestions they are welcome as well. I just think that this is as good a time as any to come up with some standardized nomenclature.

Also, I currently have statistics for the following situations:

  • 5v5
  • 5v5 Home
  • 5v5 Road
  • 5v5 Close
  • 5v5 Tied
  • 5v5 Up1
  • 5v5 Up 2+
  • 5v5 Down 1
  • 5v5 Down 2+
  • 5v5 Leading
  • 5v5 Trailing
  • 5v4 PP
  • 4v5 SH
  • Zone start adjusted data for all of the above except 5v4 SH and 4v5 SH.

If there is interest I may consider adding other situations. For example, first period, second period, third period, 4v4, 5v5 close home and 5v5 close road. Would anyone find these or any other situation interesting to look at?

Also feel free to consider the comments of this post the place where you can officially make any other suggestions of upgrades/enhancements you would like to see made to stats.hockeyanalysis.com. I can’t make any promises I will do implement them but I hope to make some upgrades over the summer.

Update: ¬†Added ‘D’ to the suffix list which stands for differential. So ASAGD would stand for Attempted Shots At Goal Differential which is the equivalent of corsi differential in use now. Might consider adding Rel but need to consider if it is necessary or not. Thoughts?
