The Performance Points Committee is a panel of well-versed players and developers who facilitate and approve updates to the performance points and star rating algorithms. Their goal is to help osu! developers push changes faster and with more community coordination.
The Performance Points Committee's responsibilities include:
When a new difficulty calculation change is proposed on GitHub, the Performance Points Committee members responsible for the relevant game mode are requested to review it. Those committee members then review and test the proposal and write feedback on its GitHub page. If the committee ultimately approves of the changes, the proposal will be passed on to osu! developers for final code inspection before it is merged into the game.
The osu! developers prepare merged proposals to be deployed in batches. A deployment recalculates star ratings for all beatmaps and performance points for all scores and users. The Performance Points Committee helps write the news post that accompanies each deployment.
The Performance Points Committee mainly operates in the Performance Points Discord server, with some game modes also having separate servers. The committee also maintains a Twitter account used for official announcements and difficulty calculation related news.
Members of the committee are hand-picked by osu! developers and/or other committee members and consist of people with a lot of experience working on the difficulty calculation system.
The osu! panel was first announced to the public through the November 2021 Performance Points & Star Rating Updates news post in response to a community survey held earlier that year.
