Built a better stat than one we publish? Send it. We will try to break it, and if it holds up, it goes on the site with your name on it.

The deal

1. We read the work and try to validate the findings ourselves, on our own data.
2. If it improves on what we offer now, we add it to the site with a citation to you as the author.
3. Anyone whose work is included gets a free PH Pro subscription once Pro is paywalled.
4. Not everything gets in. When we pass, we explain the decision when we can.

Work we have adopted

• Contact %, Aaron Knodell (Puck Over the Glass). How often a goalie gets a piece of the puck. Our replication found it repeats from year to year better than save percentage. Glossary: Goalies
• FO value, JP Gambatese (NJ Devils Advocates). What a faceoff win is worth, in goals. Rebuilt on our play-by-play, our table matches every value he published to within 0.0001 of a goal. Glossary: FO value
• Blocked-shot xG, The Bucketless (2021). Recovering where a blocked shot came from and valuing the block there. It is the method our current model is built on top of. Writeup: Blocked shots
