	effective_miss_count =
	full_combo_threshold / total_imperfect_hits(&state).max(1.0);

Should this be something like full_combo_threshold / (state.max_combo as f64).max(1.0) instead? Looking at osu's code it does this

That's true, good catch 😄

Testing will be very light for this update, at least for the time being. osu-tools has some issues preventing me from using it this time and it's way too slow anyway so I'll be waiting for the next score data dump and test against that but it'll likely be a month or two until that's available.

Actually, the data dump already includes scores with data post-update so I wrote a test suite which already caught a bunch of bugs and should give a lot more confidence in my implementation.
