GROOVE RADAR

Introduced in DDRMAX -DanceDanceRevolution 6thMIX-, the GROOVE RADAR (グルーヴレーダー) is a graphical representation of a song difficulty using a pentagon shape.

Originally meant to be the successor to the traditional Feet/Number Level system, both the Feet/Number Level and GROOVE RADAR have been used since DDRMAX2 -DanceDanceRevolution 7thMIX- due to negative reception over the GROOVE RADAR being the only representation of song difficulty.

Starting from DanceDanceRevolution (2014), the GROOVE RADAR numerical values for a chart are always shown on the song select screen. Different values will appear on the GROOVE RADAR depending on the difficulty currently selected for a song. Starting from DanceDanceRevolution SuperNOVA, the values for the GROOVE RADAR are calculated automatically by the game from the stepcharts. In previous games they were entered manually.

Before DanceDanceRevolution SuperNOVA, BEGINNER charts had no Groove Radar data at all.

The GROOVE RADAR was removed from DanceDanceRevolution arcade titles in DanceDanceRevolution WORLD.

Note: The GROOVE RADAR calculations are derived from DanceDanceRevolution (2013) but are valid for later installments of the DanceDanceRevolution arcade series.

STREAM

STREAM (全体密度) is denoted as the amount of sets of steps that are right after one another (step density) in the song. The song with the highest STREAM values is EGOISM 440, which has Single and Double CHALLENGE charts with STREAM values of 226 and 270, respectively.

It is actually calculated as the average number of steps per minute, calculated as the following:

Average Step Density = 60 × (Steps + Shock Arrows) ÷ Song Length (sec)

The Average Step Density is the average number of steps per minute, always rounded down to the nearest whole number. The Song Length is usually determined by the time between the song's beginning (usually right when the music starts) and end (when the "CLEARED" message appears). As of DanceDanceRevolution X, any Shock Arrows present in the chart will also contribute towards the Average Step Density.

  • If Average Step Density is equal to or less than 300, STREAM value = Average Step Density ÷ 3.
  • If Average Step Density is equal to or greater than 300,
    • and the play style is Single, STREAM value = (Average Step Density - 139) × 100 ÷ 161;
    • or the play style is Double, STREAM value = (Average Step Density - 183) × 100 ÷ 117.
Examples
  1. Synergy For Angels (Single EXPERT): 535 notes in 114 seconds, Average Step Density = 281, STREAM = 93.
  2. EGOISM 440 (Single CHALLENGE): 811 notes in 96.545 seconds, Average Step Density = 504, STREAM = 226.
  3. Triple Journey -TAG EDITION- (Double CHALLENGE): 712 notes in 102.5 seconds, Average Step Density = 416, STREAM = 199.
  4. POSSESSION (20th Anniversary Mix) (Double CHALLENGE): 751 notes + 132 Shock Arrows in 118.895 seconds, Average Step Density = 445, STREAM = 223.

    • CHALLENGE: EGOISM 440 (270)
Scoring

The player's STREAM rating on their MY GROOVE RADAR is added by way of taking the player's score on the chart, dividing it by 1,000,000, then multiplying it by that chart's STREAM value, and dividing it by 10. For example, if the player got a score of 699,300 on MAX 300's Single EXPERT chart (which has a STREAM value of 143), their STREAM rating on their MY GROOVE RADAR would reach 100. DanceDanceRevolution (2014) was the only game where it was possible for the player to reach a 200 STREAM rating on their MY GROOVE RADAR without needing a Perfect Full Combo on the charts with the highest STREAM values. In this case, the player would need a score of at least 884,960 or 740,750 on EGOISM 440's Single and Double CHALLENGE charts, respectively.

VOLTAGE

VOLTAGE (最大密度) refers to the peak density of the notes of the song. It is the highest density of notes that appear on the screen at once in one measure (four beats). Charts that feature sections very densely packed with notes and high average BPMs generally have high VOLTAGE values. The chart with the highest VOLTAGE rating is 's Single CHALLENGE chart, with 262.

To calculate VOLTAGE, the first step is to find the average BPM of the song. It is calculated as the following:

Average BPM = 60 × Song Length (beats) ÷ Song Length (sec)

The Song Length variable is measured in quarter beats and seconds. Both are measured from the beginning, usually right as soon as the music starts, all the way to the end when it says "CLEARED". Songs that run at very high BPMs for the majority of the song will commonly have a high average BPM. Once the average BPM is found, the next step is to find the Peak Density, which is the maximum number of notes, including Shock Arrows, that occur in four consecutive beats. Take the average BPM of the song (or chart, if it has its own BPM changes and stops), multiply it by the Peak Density (usually a number between 8 and 16), and then divide by 4 to find the Average Peak Density value.

Average Peak Density = Average BPM × Peak Density ÷ 4

Note that the resulting Average Peak Density is rounded down to the nearest integer. If the song/chart in question runs at a constant BPM, use the BPM of the song/chart instead.

  • If the Average Peak Density is equal to or less than 600, VOLTAGE = Average Peak Density ÷ 6.
  • If the Average Peak Density is equal to or greater than 600, VOLTAGE = (Average Peak Density + 594) × 100 ÷ 1194.
Examples
  1. Ishtar (Single/Double EXPERT):
    • 276 beats in 106.1538 seconds,
    • Average BPM = 156,
    • Peak Density = 12,
    • Average Peak Density = 468,
    • VOLTAGE = 78.
  2. Blew My Mind (Single/Double CHALLENGE)
    • 520 beats in 99.9474 seconds,
    • Average BPM = 312.16,
    • Peak Density = 23,
    • Average Peak Density = 1794,
    • VOLTAGE = 200.

Scoring

The player's VOLTAGE rating on their MY GROOVE RADAR is increased based on the maximum combo they have received on the chart. A full combo means that the player will receive the maximum VOLTAGE rating from that chart. For example, Blew My Mind's Single CHALLENGE chart has a VOLTAGE value of 200. If the player wanted to raise their MY GROOVE RADAR's VOLTAGE rating to 160, they would need to achieve a MAX COMBO of at least 534, as said chart has 665 notes and 2 Shock Arrows.

AIR

AIR (ジャンプ度) refers to the total number of jumps and Shock Arrows in the chart. POSSESSION (20th Anniversary Mix)'s DOUBLE CHALLENGE chart holds the current highest AIR value of 224.

It is calculated similarly to STREAM except only jumps and Shock Arrows are involved:

Average Air Density = 60 × (Jumps + Shock Arrows) ÷ Song Length (sec)

As with STREAM, Average Air Density is an integer number. On Double charts, if a Shock Arrow occurs right next to a jump, both that Shock Arrow and jump count towards AIR.

  • If Average Air Density is equal to or less than 55, AIR = Average Air Density × 20 ÷ 11.
  • If Average Air Density is equal to or greater than 55,
    • and the play style is Single, AIR = (Average Air Density + 36) × 100 ÷ 91;
    • or the play style is Double, AIR = (Average Air Density + 35) × 10 ÷ 9.
Examples
  1. PARANOiA Revolution (Single CHALLENGE): 90 jumps in 110.167 seconds, Average Air Density = 49, AIR = 89.
  2. Right on time (Ryu☆Remix) (Single CHALLENGE): 181 jumps + 63 Shock Arrows in 99.866 seconds, Average Air Density = 146, AIR = 200.
  3. BRILLIANT 2U (Double DIFFICULT): 72 jumps in 75.2 seconds, Average Air Density = 57, AIR = 102.

Highest AIR values per difficulty
Scoring

The player's AIR rating on their MY GROOVE RADAR is increased based on how many jumps in the chart they hit with at least a Great and how many Shock Arrows they successfully avoid. New Decade's Single CHALLENGE chart has an AIR value of 112 and 100 jumps; if the player wanted to raise their AIR value to 100 by playing that chart, they would have to successfully hit at least 90 jumps in the chart.

FREEZE

FREEZE (踏みっぱ度) is denoted as the total length of the chart's Freeze Arrows. D2R ("FREEZE" Special)'s charts currently have the highest FREEZE value of 200.

It is calculated as:

FA Rate = 10,000 × FA Total Length (beats) ÷ Song Length (beats)

FA Rate is the average rate of Freeze Arrows. If two Freeze Arrows appearing at once start at the same time, only the longer end is counted.

  • If FA Rate is equal to or less than 3,500, FREEZE value = FA Rate ÷ 35.
  • If FA Rate is equal to or greater than 3,500,
    • and the play style is Single, FREEZE value = (FA Rate + 2484) × 100 ÷ 5,984;
    • or the play style is Double, FREEZE value = (FA Rate + 2246) × 100 ÷ 5,746.
Examples
  1. Chinese Snowy Dance (Single BASIC): 85.0 total FA length in 300 beats, FA Rate = 2833, FREEZE = 80.
  2. D2R ("FREEZE" Special) (Single CHALLENGE): 239.0 total FA length in 252 beats, FA Rate = 9,484, FREEZE = 200.

Scoring

The player's FREEZE rating on their MY GROOVE RADAR is increased based on how many Freeze Arrows they successfully clear with an O.K. judgement in the chart. D2R ("FREEZE" Special)'s Single CHALLENGE chart has 67 Freeze Arrows, and if a player wanted to raise their FREEZE rating to 150, they would need to successfully clear 51 Freeze Arrows in that chart.

CHAOS

CHAOS (変則度) refers to the amount of steps that do not match well with the beat of the song. The song with the highest CHAOS ratings is 鳳, which has Single and Double CHALLENGE charts with CHAOS values of 310 and 312, respectively.

In practice, it is determined by multiple factors.

The first factor determining CHAOS is the number of non-4th (red) notes, determining the chart's Total Chaos Base Value. Each note has a Chaos Base Value assigned to it, calculated as the following:

(Note Quantization ÷ Interval from Last Note) × Note Color Value × Number of Arrows
  • Note Quantization: 4th, 8th, 12th, 16th, 24th, 32nd, 48th, or 64th.
  • Interval from Last Note: How far this note is from the previous one, based on its Note Quantization.
  • Note Color Value: The color of the note as viewed with the NOTE ARROW COLOR option. Red (4th) notes have a value of 0, blue (8th) notes have a value of 0.5, yellow (16th) notes are 1, and green (12th, 24th, 32nd, etc.) notes are 1.25.
  • Number of Arrows: A single note yields 1, a jump yields 2, and a Shock Arrow yields 4 or 8. On Double charts, a single note occurring concurrently with a four-lane Shock Arrow yields 5 while a jump occurring concurrently with a four-lane Shock Arrow yields 6.
  • Note: The first note's Chaos Base Value is always 0 regardless of its color.
Example: Valkyrie dimension (Single CHALLENGE), with 4,456.16.

The second factor determining CHAOS is Total BPM Delta, the sum of the BPM changes in the chart. As an example, Valkyrie dimension: 90 → (gradual speedup) → 240 → 480 → (stop) → 744 → (stop) → 186 → 93 → 186 → (24 stops) → 186 → 93 → 744 → 186 → (stop) → 186 → 46.5 → 390. The Total BPM Delta value is calculated as the change from one BPM to another (186 → 93 = 93). In the case of gradual BPM changes, simply take the highest BPM value, subtract it from the lowest, and get its absolute (non-negative) value. In the case of stops, use the BPM that is immediately used after the stop. If the song has no BPM changes or stops, the Total BPM Delta is 0. Valkyrie dimension's Total BPM Delta is 7,941.

The third factor determining CHAOS is song length, in seconds. Valkyrie dimension has a song length of 114.246 seconds. This affects the Average BPM Delta (per minute), which is calculated as:

60 × Total BPM Delta ÷ Song Length (sec)

Valkyrie dimension has an Average BPM Delta of 4,170.468624.

The fourth factor determining CHAOS is the Chaos Degree, calculated as:

Total Chaos Base Value × (1 + (Average BPM Delta ÷ 1,500))

Valkyrie dimension's Single CHALLENGE chart has a Chaos Degree of 16,846.

The fifth and final factor determining CHAOS is the Unit Chaos Degree, calculated in integer form as:

Chaos Degree × 100 ÷ Song Length (sec)
  • If the Unit Chaos Degree is equal to or less than 2,000, CHAOS = Unit Chaos Degree ÷ 20.
  • If the Unit Chaos Degree is equal to or greater than 2,000,
    • and the play style is Single, CHAOS = (Unit Chaos Degree + 21,605) × 100 ÷ 23,605;
    • or the play style is Double, CHAOS = (Unit Chaos Degree + 16,628) × 100 ÷ 18,628.
Examples
  1. Fascination MAXX (Single BASIC): Total Chaos Base Value = 547.99359 and Total BPM Delta = 3,500 in 101.225 seconds, Unit Chaos Degree = 1,290, CHAOS = 64.
  2. Valkyrie dimension (Single CHALLENGE): CHAOS = 153.
  3. CHAOS (Double CHALLENGE): Total Chaos Base Value = 4,116 and Total BPM Delta = 7,480 in 87.882 seconds, Unit Chaos Degree = 20,628, CHAOS = 200.

Scoring

The player's CHAOS rating on their MY GROOVE RADAR is increased when they clear a chart with as few Misses as possible. CHAOS' Double CHALLENGE chart has a CHAOS value of 200, meaning that if the player wanted to raise their MY GROOVE RADAR's CHAOS rating to 160, they would need to clear the chart with less than 72 Misses, assuming their CHAOS rating is above 144 already.

MY GROOVE RADAR

MY GROOVE RADAR (マイグルーヴレーダー), introduced in DanceDanceRevolution SuperNOVA2, is the player's own GROOVE RADAR that rates them based on their mastery of the five aspects of the GROOVE RADAR. It starts at 0 for all five parameters and increases as the player plays and completes songs. The values increase by 10% of the calculated fulfilled GROOVE RADAR values for the chart (e.g. if a player scores a MAX COMBO of 508 on POSSESSION's Single EXPERT chart, which has a VOLTAGE value of 161, the player's MY GROOVE RADAR VOLTAGE rating will increase by 13, rounded down from 15% of 134). To advance their MY GROOVE RADAR past 100, the player must achieve 100 on all five aspects first.

This feature was discontinued in DanceDanceRevolution A.

Calculation in older games

Since the introduction of the MY GROOVE RADAR feature in DanceDanceRevolution SuperNOVA2, various charts that have more than 100 in any aspect of the GROOVE RADAR have had their ratings in said aspect(s) lowered several times due to the introduction of various songs that have greater parameters than them. This is because prior to DanceDanceRevolution (2014), any new chart that was deemed to go over 200 in any aspect of the GROOVE RADAR with previous GROOVE RADAR parameter calculation formulas resulted in said formulas being adjusted to make that chart reach 200. The following section details what each of the resulting parameters must be for each aspect of the GROOVE RADAR to reach 200 in games before DanceDanceRevolution (2013).

DanceDanceRevolution SuperNOVA2 → DanceDanceRevolution X
  • STREAM: Average Step Density must be 396 (387 on Double) for the STREAM value to be 200. Fascination MAXX's Single CHALLENGE and PARANOIA survivor MAX's Double CHALLENGE charts each had the highest STREAM rating of 200 between DanceDanceRevolution SuperNOVA2 and X.
  • VOLTAGE: Average Peak Density Per Minute must be 1,302 for the VOLTAGE value to be 200. PARANOiA ~HADES~'s CHALLENGE charts both had the highest VOLTAGE rating of 200 before DanceDanceRevolution X2.
