Advanced Stats Glossary of Terms
As requested, this will be the glossary of advanced stats terms used in the Grading the Flyers series.
- TOI/60
Time on Ice per 60 minutes. This calculates even-strength time on ice for the player per 60 minutes of team play. Two things to notice: 1) It isn't even-strength time on ice per GAME, as it adjusts for over-time periods; and 2) It is in decimal form, so 11.5 is eleven minutes and thirty seconds. - QualComp
This stands for Quality of Competition. Gabe Desjardins explains it best on his site (Behind the Net FAQ page) but "It is the average On/Off-Ice +/- of the opposing players a player faces". An excellent example is given at the link above. He goes into further detail here. - QualTeam
This stands for Quality of Teammates and is calculated the same way as QualComp. A more detailed explanation can be found here. - G/60
This stands for Goals per 60 minutes and counts only even-strength time. Take the number of even-strength goals scored for the player, divide them by his total even-strength time on ice and multiply by 60. - A1/60
Assists are both primary and secondary, based on whether they were the last player to touch the puck prior to a goal, or the second to last. A1/60 counts only those where the player was the last to touch the puck. Eric T. wrote about why primary assists matter and secondary assists don't, so we've started using A1/60 a lot more frequently. - PTS/60
Points per 60 is the exact same as G/60, but includes assists. Again, even-strength only. - GFON/60
This stands for Goals For while On the Ice per 60 minutes. Every time a player is on the ice for a Flyers even-strength goal (excluding empty-net situations), the player is given a GFON. Then divide by his total even-strength time on ice and multiply by 60. - GAON/60
Goals Against while On the Ice per 60 minutes is the exact same as GFON/60, but counts opponent's goals. - OSZ%
This is Offensive Zone-Start Percentage. For every even-strength non-empty net faceoff, the player receives either an Offensive, Neutral, or Defensive Zone Start. The percentage is calculated by dividing the number of Offensive Zone Starts by the total number of Offensive AND Defensive zone starts for the player. - Fen%
This stands for Fenwick Percentage, which is the total number of even-strength shots the Flyers got through to the net (Goals, Shots on Goal, and Missed Shots) while the player was on the ice divided by the total number of even-strength shots both the Flyers AND the Opponent got through to the net. - Cor%
This is Corsi Percentage, which is the exact same as Fenwick except it includes blocked shots. Think of Fenwick as "shots that got through the defense" and Corsi as "all shots directed towards the net". - PTake/60
This stands for Penalties Taken per 60 minutes. It includes only non-coincidental penalties taken, divides by 5-on-5 time on ice, and multiples by 60. - PDraw/60
This is Penalties Drawn per 60 minutes and is calculated the same way as Penalties Taken per 60 minutes.
If you have any further questions, almost all are answered at Gabe Desjardins' BehindtheNet.ca's Frequently Asked Questions Page, or at BehindtheNethockey.com.

Thanks for the explanations. Do you happen to have a few players to show where their Fenwick and Corsi are noticably different? Thanks
Example:
Chris Pronger: .552 Fenwick, .537 Corsi
Braydon Coburn: .538 Fenwick, .536 Corsi
Lukas Krajicek: .471 Fenwick, .461 Corsi
I would normally give you a link, but these numbers were acquired from Vic Ferrari’s Time on Ice site. Gabe Desjardins told me he’s changing his Corsi scores to a percentage (as above) this summer and hopefully adding a Fenwick. So, until that happens, these numbers will only be found a) in the Grading the Flyers series; or b) upon request.

Maybe try Brent Sopel?
He blocks a TON of shots, so he might have a ridiculous Fenwick-Corsi spread.
Well, the Blackhawks as a team were a ridiculous .580 Fenwick and .567 Corsi, so Sopel’s .551 Fenwick and .540 Corsi aren’t exactly ridiculous put in that context.
Sharp, Toews, Campbell, and Hossa however, were all .600 Fenwick or above though.

Has anyone done an analysis using these types of advanced stats on the teams that advanced past each round of the playoffs? I’d be interested to see if those who did/didn’t advance match those who should have, statistically. Or can that be done?
Either way, thanks for the glossary.
Well, I’m not sure on every series, but Gabe Desjardins did phenomenal work throughout the playoffs over at Behind the Net, and I know for a fact he spent a lot of time on the Canadiens (the Caps and Pens were the better team), the Sharks (specifically the Avalanche series which they dominated), and at least one on the Blackhawks (They won the first two rounds despite being only marginally better).
If you are at all interested in these advanced stats, he’s the guy I get about 80% of my data from. I can’t say enough good things about him and right now he’s doing work on the World Cup.

Thank you. But Travis runs the site, Ben is the off-topic comedic genius and I’m the stats geek. I think we all work well together.
I’m just glad people are starting to actually get interested in these stats.

I hadn’t realized the troika thing was in effect.
OK. You guys run a great site.

haha, no problem.
Don’t get me wrong, I appreciate the recognition, I just like to give credit where it’s due.

I think of them more as like a trinity.
Travis, the blog overlord, creator of topics and punisher of trolls.
Geoff, descends and tries to teach us about all the good things that can be found by looking deeper into hockey, in order to believe more than just what our eyes tell us.
Ben, floats around saying and doing hilarious things, giving the site warmness and continuing harmony.
I hope this comment appeases the trinity.

Remember up there ^^^ when I said "You run a great site. Been looking for you for a long time."?
This is the kind of thing I meant. I’m thinking I might just never leave. The Flyers stuff is a bonus, I admit. You are seriously warped Mr. Fox. Seriously. I like it.

Slow learner, me.
How did you get the “New Zealand’s 4th best Philadelphia Flyers fan” line above the “by ToddtheFox”?

haha, just so we don’t have another Kreider on our hands – Yeah, Shaun, I’m making fun of you. Again! – have you discovered the amazingness of the ‘z’ key?

haha, oh man!
It’s amazing, especially in game threads. When there are new comments, you can hit ‘z’ and it automatically goes to the next new comment, marking the one you were just on as read. If you read a comment but want to keep it unread, you hit ‘c’ to get to the next new comment, eventually leading you back to the one you were on.
So, for example, when I opened this thread up, as soon as the page loaded I hit ‘z’ and it took me straight to your comment, without having to scroll down. I’ll hit ‘z’ again and go to the next new comment, whether it be a reply to the first comment, a new one at the bottom, or anywhere in between.

That is amazing. Thanks!
But of course…and you just knew this would happen…I want more.
Got more?

haha, that’s about all I got. Check the box above all the comments but below the stories. There are a few other shortcuts, but ‘z’, ‘c’, and ‘r’ are my favorites.

I cannot count
the number of people who have been “saved” by learning about the ‘z’ key.
"I did my walk of shame this morning and everyone was so much nicer," she said. "People were inviting me to parties at 9 a.m."
You can just sacrifice Crosby. No need to use the effigy.
And I think it’s less a Trinity that a Menage’ a Trois of hockey goodness.

A big area of interest for me is data visualization and the information Gabe puts out is in the perfect format to develop with…
My only problem is that I can’t think of any good visualization make with them. By visualizaion, I mean any kind of charts, graphics, etc. If anyone has any ideas using any number of these kinds of stats, let me know. I really want to make something related to this stuff.
Maybe a bar graph? Put the team scores at the halfway point of the x axis and show each player’s Corsi and Fenwick along the y axis?
As far as the others go… Not sure.

Data Visualization
There’s some really cool stuff out there, but I feel like it’s underappreciated. A good visualization goes a long way towards helping people make sense of numbers. There’s some interesting blogs out there on the topic, and it’s nice to see what goes above and beyond the normal graphs and charts.
I think you should be thinking about your objective before you think of a visualization. Are you trying to compare players against each other? Maybe you want to understand the distribution of numbers of a particular stat (you could put them in a histogram and point out which buckets some key players fall in).
Or perhaps you want to regress one variable against another (often goal differential, if you are trying to figure out how well a stat is correlated with goals). I did a stats post on SCH a little while back where I used some techniques to shade these graphs by probability, and also point out some of the points. I think I went overboard on this, and perhaps it’s more useful to show deviations from what you expect (the regression line) by drawing some lines from that to a point for a player or game.
There’s a whole world of possibilities out there — I’d love to see what you can come up with, because I feel like I’m struggling to figure out how to display data in a digestible manner too.
Exactly… data visualization can be art is done right and that’s what I’m trying to do. With these advanced stats however, there’s so much to choose from and I’m not even sure where to begin.
I did make something for trades during last season you should check out.
Let me know what you think.
But back on topic, if you have any ideas for something to be visualized, let me know… that’s my problem :), what to do
If you are graphically inclined, I would just have a go at putting the numbers on a spreadsheet and fiddle around with things that look good to you. Simplicity is generally the key for graphs.
I’ve made a few scatter plots with regressions just out of interest’s sake and they look ok. I think the main thing, especially if you want to do a fanpost or something, is that it is easily and quickly read and understood. And that is what I’m having most trouble with

This would all be done using dynamic data pulled from the internet and visualized using a javascript library. No excel.
Your analysis of advanced stats would be more advanced than mine then.

Hah… just cause I can take premade data and shove into a pretty form doesn’t mean I always understand whats going on ;). Finally understanding all of this advanced stuff sparked my interest in visualization again (see the link I posted in the other reply for my other work) and I really want to do my hockey stuff
This is very helpful and gives me more insight into aspects of the game I never thought of before. I have seen these advanced stats in places and kind of got what some mean, but not all. Ones I always saw thrown around were Fenwick and Corsi and I had no clue what they are but now I know, and Knowledge is Power!! lol
