Then for the kth step,

Step Score = J * (K * U + Q)

where

• B = 1000000
• S = N*(N+1)/2, N = number of steps in song
• U = floor(B / S)
• J = 10 if Perfect, 5 if Great, 0 otherwise
• Q = B - U*S if the last step, 0 otherwise

4th

Official description of the scoring system: https://web.archive.org/web/20070204141156/http://www.konami.jp/bemani/ddr/jp/am/ddr4th/

Variant of 3rd with difficulty multiplier and end of song grade and combo bonuses.

Step Score = J * (K * U + Q)

where

• U = floor(B / S)
• J = 10 if Perfect, 5 if Great, 0 otherwise
• Q = B - U*S if the last step, 0 otherwise

At the end of the stage a bonus is applied:

• Grade Bonus = 10000000 for AAA, divide by 10 for each lower rating down to 100 for D, 0 for E
• Combo Bonus is accumulated per step:

Step Combo Bonus = C * J'

where

• C = combo count after step if life bar not empty, 0 otherwise
• J = 55 if Perfect, 33 if Great, 0 otherwise
