Score Calculation
Table of contents
Judgement
The following judgement is possible for each note:
- PGREAT (perfect great)
- GREAT
- GOOD
- BAD
- POOR
Each charge note (same for hell charge note) count as two notes - one in the beginning, one at the end. Using LEGACY option turns that into just one in the beginning.
For timing windows, refer to this page.
Excessive POOR (空POOR)
Excessive POOR is a POOR that happens when you press a button again, right after the note was already processed, or when you press the button slightly earlier than the beginning of BAD window. See this page for more details.
To calculate:
空POOR = MISS_COUNT - COMBO_BREAK
EX-SCORE
EX score is the only scoring system in the game. Its rules are simple:
- PGREAT gives you 2 points.
- GREAT gives you 1 point.
DJ LEVEL
DJ level on the result screen is calculated using EX-SCORE, compared to the theoretical maximum score possible for the chart. If you take the ratio (EX_SCORE / MAX), you can see what grade you will get:
| Grade | EX score ratio | Percentage |
|---|---|---|
| AAA | 8/9 or above | >= 88.89% |
| AA | 7/9 or above | >= 77.78% |
| A | 6/9 or above | >= 66.67% |
| B | 5/9 or above | >= 55.56% |
| C | 4/9 or above | >= 44.44% |
| D | 3/9 or above | >= 33.33% |
| E | 2/9 or above | >= 22.22% |
| F | Under 2/9 | < 22.22% |
What is “max-“ ?
You will often hear people talk about scores relative to a grade, for example, “AA-3” to mean 3 points under the AA requirement, or “AAA+10” to mean 10 points above the AAA requirement.
If you get 8.5/9 (94.44%) or higher, it is considered a MAX- score. While MAX- is not a rating displayed on the result screen, it does show up in other parts of the interface, and you will hear about players refer to scores in this way.
Getting a MAX (sometimes MAX+0, MAX-0, or 理論値) refer to obtaining the theoretical maximum value of 100%, PGREAT on every note.
All time records
To put things in to perspective, for AC scores, as of January 2022:
- All SP top scores are in MAX- range. Two songs (Mosaic and GRID KNIGHT L) have been MAX’d.
- All DP top scores have AAA or above, except Mare Nectaris.
DJ POINT
DJ point is a numerical score given to each chart. It is displayed in the song select screen (in the bottom left corner). It is a function of your best EX score and the best clear lamp on the chart; you don’t necessarily have to get the highest score and the best lamp in one attempt, it can be across multiple attempts. The clear lamp can also be from a previous version.
DJ points aren’t commonly used when comparing scores; the EX-SCORE is used instead.
DJ POINT Formula
\[\begin{align*} DJPOINT = \frac{EXSCORE \times (100+C+L)}{10000} \end{align*}\]where:
- C is clear lamp percentage bonus
- full combo = 30
- ex-hard = 25
- hard = 20
- normal clear = 10
- easy clear = 5
- assist clear or fail = 0
- L is DJ level percentage bonus
- AAA = 20
- AA = 15
- A = 10
- B or below = 0
Total SP / DP DJ POINT
There is also a total DJ POINT for SP and another for DP; this is the sum of all DJ points for all songs in the game. Songs have multiple charts, but only the highest for SP and the highest for DP are used for each song when calculating this total. This total is displayed when you card in, and an updated value is shown when you card out. The total value isn’t commonly discussed or compared against others, but it is sometimes used as a requirement to unlock hidden songs and charts in both arcade releases and Infinitas.
