Scoring and Judgment

The scoring system and judgment system in Bemuse focuses on both accuracy and combo.

Judgment

When hitting the note, the accuracy of your button press will be judged according to this table:

Judgment	Normal	Level5	Level4	Level3	Beginner	Score
Meticulous	20ms	21ms	22ms	23ms	24ms	100%
Precise	50ms	60ms	70ms	80ms	100ms	80%
Good	100ms	120ms	140ms	160ms	180ms	50%
Offbeat	200ms	200ms	200ms	200ms	200ms	0%

The different timegates are designed to make the game easier for beginners, with a gradual increase in difficulty the harder the song gets. They are divided as follows:

Timegate	Song Level
Beginner	1-2
Level3	3
Level4	4
Level5	5
Normal	6+

The final score is split into 2 parts:

• 500000 for accuracy
• 55555 for combo bonus

Each combo has an associated score.

Combo number	Combo score
0	0
1–22	1
23-50	2
51-91	3
92–160	4
161~∞	5

Combo bonus is the sum of combo score for each hit, divided by maximum possible value, times 55555.

Example: There are 100 notes. 60 notes have been hit, I missed a note, and hit 39 other notes.

• Obtained combo score = 108 for first 60 notes + 56 for 39 other notes = 164
• Maximum possible combo score = 237
• Combo bonus = 164 / 237 * 55555 = 38443

Grading

After playing the game, the grade is calculated according to this table:

Grade	Minimum Score
F	0
D	300000
C	350000
B	400000
A	450000
S	500000
