Well, the pace didn't last long, but we're back with Part V - Rink Repair Statistics

Probably, this is the least hockey related page of the website, but hey, we can do it, and it's actually pretty easy, so why not?

The STOP events as listed in the Play-By-Play HTML summaries since the 2002/03 season on the NHL.com website contain the reason(s) for the stop. While most of them are game-based, such as ICING or OFFSIDE, one of the more rare ones caught our eye: RINK REPAIR. We decided to collect these stops and rank NHL home teams as well as NHL arenas by the amount of rink repairs that happened. We filter out the occasional venues, such as outdoor stadiums for NHL special events or the foreign arenas for the European showdown games.

Since we already parse practically all events from the Play-By-Play summaries (or PL), and classify them by types, we already have a collection of STOP events. And we also detect and catalog the reasons for the stoppages, so it is an easy Mongo query to extract all rink repairs incurred. We then aggregate them by locations and teams, and create SQL tables for easy quick display of the data.

And so we were able to assemble a nice set of tables displaying the level of maintenance in the rinks around the league. Here's a look at the 2016/17 season:
