A tool to visualize the songs that make up your PA Skill in the Bemani rhythm game Polaris Chord.

In Polaris Chord, your PA Skill is calculated by taking your 30 most valuable scores and averaging them. A score is calculated based on two factors: the chart constant (basically the game's internal difficulty rating for the song being played) and the achievement rate (how accurately and on-time the notes were hit). The chart constant is partially hidden - the game only gives out whole numbers, but internally, there are decimals, so e.g. two songs can be labeled as "12" in game, but internally, one could be 12.1 and the other could be 12.7, which affects how valuable the score is.

This tool calculates this score for each song and displays this info, helping users determine which songs are worth grinding to raise their PA Skill. The data can be viewed in either a table of all of their scores, or an image grid of their best 30 scores.
