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.

MY GROOVE RADAR (マイグルーヴレーダー) 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.

== 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 &rarr; 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~|PARANOiA ~HADES~]]'s CHALLENGE charts both had the highest VOLTAGE rating of 200 before [[AC DDR X2|DanceDanceRevolution X2]].
* AIR: Average Air Density must be 109 for the AIR value to be 200. DYNAMITE RAVE ("AIR" Special)'s CHALLENGE charts had an AIR rating of 200 before the introduction of TWINKLE♡HEART's CHALLENGE charts in [[AC DDR X3|DanceDanceRevolution X3 VS 2ndMIX]].
* FREEZE: FA Rate must be 9,484 (9,246 on Double) for the FREEZE value to be 200. D2R ("FREEZE" Special)'s CHALLENGE charts have remained the charts with the highest FREEZE rating of 200 since their introduction.
* CHAOS: Unit Chaos Degree must be 25,605 (20,628 on Double) for the CHAOS value to be 200. CHAOS' CHALLENGE charts have remained the charts with the highest CHAOS rating of 200 since their introduction.
; DanceDanceRevolution X2
* STREAM: Average Step Density must be 461 (417 on Double) for the STREAM value to be 200. 888's CHALLENGE charts became the charts with the highest STREAM rating of 200 until EGOISM 440's CHALLENGE charts were introduced in DanceDanceRevolution (2014).
* VOLTAGE: Average Peak Density Per Minute must be 1,329 for the VOLTAGE value to be 200. POSSESSION's EXPERT and CHALLENGE charts became the charts with 200 VOLTAGE.
* AIR: Remained unchanged until X3 VS 2ndMIX.
* FREEZE: Has remained unchanged from SuperNOVA2.
* CHAOS: Has remained unchanged from SuperNOVA2.
; DanceDanceRevolution X3 VS 2ndMIX
* VOLTAGE: Average Peak Density Per Minute must be 1,530 for the VOLTAGE value to be 200. London EVOLVED ver.A's CHALLENGE and Single EXPERT charts had 200 VOLTAGE in their introduction in X3 VS 2ndMIX.
* AIR: Average Air Density must be 115 (111 on Double) for the AIR value to be 200. TWINKLE♡HEART's CHALLENGE charts had 200 AIR when introduced in X3 VS 2ndMIX.
== Trivia ==
* In [[CS DDR SuperNOVA2 NA|DanceDanceRevolution SuperNOVA2 CS (America)]], all charts are shown with a much higher STREAM value on the GROOVE RADAR than they normally would.
