+- **nhl_regular_season.csv** – Final regular-season standings for six NHL teams from 1999–00 through 2008–09, retrieved from the [official NHL standings API](https://api-web.nhle.com/v1/standings-season) using [`fetch-nhl-standings.py`](../python/fetch-nhl-standings.py). Includes season and end date, team name and abbreviation, games played, points, and points percentage (`points / (2 × games played)`, on a 0–1 scale). The cancelled 2004–05 season has no rows because of the league-wide lockout.
