This class was only used in two places, both on the results screen, but was holding references to `OsuPlayfield` game-wide (due to unrelated issues, but still). Because I can't really think of future use cases for this, and running the calculation twice at results screen isn't a huge overhead, let's just do that for now to keep things simple.
