-Introduced in [[AC DDRMAX|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 [[AC DDRMAX2|DDRMAX2 -DanceDanceRevolution 7thMIX-]] due to negative reception over the GROOVE RADAR being the only representation of song difficulty. Starting from [[AC DDR 2014|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. Before [[AC DDR SuperNOVA|DanceDanceRevolution SuperNOVA]], BEGINNER charts had no Groove Radar data at all.

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 [[AC DDR WORLD|DanceDanceRevolution WORLD]].
 '''Note:''' The GROOVE RADAR calculations are derived from [[AC DDR 2013|DanceDanceRevolution (2013)]] but are valid for later installments of the DanceDanceRevolution arcade series.

 == VOLTAGE ==
-'''VOLTAGE''' (最大密度) refers to the peak density of the arrows of the song. It is the highest density of arrows that appear on the screen at once in one measure (four beats). Charts with sections very densely packed with notes and featuring high average BPMs generally have high VOLTAGE values. The chart with the highest VOLTAGE value is [[ACE FOR ACES]]' Single CHALLENGE, with 260.
+'''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 value is [[ACE FOR ACES]]' Single CHALLENGE chart, with 260.
-To calculate VOLTAGE, find the average BPM of the song first. The average BPM is calculated as:
+To calculate VOLTAGE, the first step is to find the average BPM of the song. It is calculated as the following:
 <pre>Average BPM = 60 × Song Length (beats) ÷ Song Length (sec)</pre>
-where Song Length is determined both in beats and in seconds; both are measured from the beginning (usually right when the music starts) all the way to the end (when it says "CLEARED"). Once the average BPM is found, find the Peak Density (the maximum number of notes, including Shock Arrows, if any, that occur in four consecutive beats) and divide by 4 to find the Average Peak Density Per Minute value, which is always an integer number. If a song has no stops or BPM changes, use the song's BPM instead.
+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.
-* If Average Peak Density Per Minute is equal to or less than 600, VOLTAGE = Average Peak Density Per Minute ÷ 6.
+<pre>Average Peak Density = Average BPM × Peak Density ÷ 4</pre>
-* If Average Peak Density Per Minute is equal to or greater than 600, VOLTAGE = (Average Peak Density Per Minute + 594) × 100 ÷ 1194.
+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.
