Great stuff as always, @Frisbetarian.

Moneypuck appears to compute their own formulation of expected goals as well. What they say about their methodology:

Awesome work, @Frisbetarian. It's good to see some correlation between the models. Shayna Goldman wrote a great article on the athletic comparing the methodology of the "core four" publicly available models (NST, Moneypuck, Evolving-Hockey and HockeyViz). Dom's model informs alot of their content but while his methodology is available, the data they use is not. I'd love to see how these all perform vs your proprietary model.

I am not up to date on the publicly available systems, as I still get the team's internal data and some tracking stuff. So thanks @durandal1707 and @burstnbloom for the info on Moneypuck, Evolving Hockey, and HockeyViz! Thanks also for that awesome Athletic article!

I will definitely test the 3 models I'm missing when I have some time. I am in the initial stages of selling my home (gulp), and am crazy busy right now.

How granular do you get with "actions"? Some are certainly easy to measure (completed pass vs. deflected pass vs. flubbed passes, etc.) but imagine it's near impossible to do others that are more fluid movements (winger went wide and took defenseman with him to open up the shooting lane).

Unfortunately, I cannot share too much here. I can tell you that what is currently available does not get as granular as your latter example, but it is more more granular than your former. I know that doesn't help much, but it's really all I can say.
