估算在节奏游戏osu!中一次得分的表现点数（pp）。计算基于准确率、连击数和失误数。
This is a simplified model. For precise pp values, a beatmap-specific calculator is needed.
Performance Points (pp) are the core measure of skill in the rhythm game osu!. A player's total pp determines their global rank. The pp value of a score is determined by complex algorithms that analyze the difficulty of a map (things like aim, speed, and patterns) and the player's performance on it.
