DanceDanceRevolution SuperNOVA2 Scoring System

After changing the scoring system in every main arcade release since DanceDanceRevolution 3rdMIX, the DanceDanceRevolution SuperNOVA2 scoring system has been largely untouched since release.

Score

The maximum score possible for a song is 1 000 000 points. Similar to the scoring system in SuperNOVA, all steps (Freeze Arrows and Shock Arrows included) in a song are scored evenly throughout the song. Due to the notescount being different each song for each difficulty, a new Step Score have to be determined every time in order to calculate the score:

Step Score (SC): 1.000.000 ÷ (Number of steps [A jump will be considered a step in scoring] + Number of freezes [A pair of freeze that starts and ends at the same time will be considered as one freeze in scoring] + Number of Shock Arrows [From DanceDanceRevolution X onwards])

The Step Score is then used to calculate the player results using all the judgment timing obtained in the song:

Score: SC x (number of Marvelous + number of OKs) + (SC - 10) x (number of Perfects) + [(SC ÷ 2) - 10] x number of Greats

In DanceDanceRevolution A, the scoring system has been changed slightly:

Score: SC x (number of Marvelous + number of OKs) + (SC - 10) x (number of Perfects) + [(SC * 3/5) - 10] x number of Greats + [(SC * 1/5) - 10] x number of Goods

The scores are always displayed as multiples of 10 if playing in Standard mode, multiples of 1 if playing in COURSE MODE.

Grade

The table below applies to both Single Play (SP) and Double Play (DP).

This new grade system changed two fundemental elements that have been a part of the series since the beginning. The highest grade available (AAA and AA) are no longer exclusive to a Full Combo as it's now obtained solely based on the points obtained. The grade system also takes into consideration the Dance Level selected by the player. The easiest Dance Levels have a more uniform score range for each letter while the hardest difficult levels have a wider range at the bottom (D) and thinner one at the top (A). A few elements are shared by every Dance Level such as the score range for an AAA and AA being the same. Similar to the previous systems, as long as the life gauge is not completely depleted, the song will be considered CLEARED and thus, receive a grade letter for the corresponding score; otherwise, it will be considered FAILED.
