Formula ported directly from resolveScore() in the gakumas-engine (MIT, open-source surisuririsu/gakumas-tools) — the same numbers Japanese community tools use. Verified against 25/25 golden test cases.
How the calculation works
- Base card score is added to Concentration and Motivation, then rounded (1st).
- Multiplied by Good Condition (if on) and the selected Stance.
- Multiplied by score buff/debuff and Poor Condition (if on), then rounded (2nd).
- Multiplied by the current turn type's multiplier (Vocal/Dance/Visual), then rounded (3rd) for the final score. If the base score is ≤ 0, it's kept as-is — no addition, multiplication or rounding applied.
Lesson score by week / difficulty
Base score for each Lesson week by difficulty, with the lesson bonus % (from gear/support cards) applied — official engine numbers, nothing made up.
