DDRA


In the (currently) newest DDR, the maximum score available for a song is still 1,000,000 points, and scores are displayed as multiples of 10 (no score will end with a digit other than 0). The value of each step or freeze (or shock arrow) is equal to:

    Step Score = 1,000,000 / (number of steps + number of freezes and shock arrows)


And based on the different step judgments

    Marvellous = Step Score
    Perfect = Step Score - 10
    Great = (Step Score *0.6) - 10
    Good = (Step Score *0.2) - 10
    O.K. = Step Score
    (anything else) = 0

Marvelous/O.K. are each worth this same value. Perfects are worth that value - 10, and Greats are worth that (value*0.6)-10, or 60% of the value of perfects minus 10. Note that in this mix, Goods are worth 20% of the value of perfects - 10 as opposed to 0 for all previous mixes. Note that the internal score used for calculation is always a floating point value, but the displayed score will be that value rounded down to the nearest 10 points.


From DDR X onward, with the addition of shock arrows step score is obtained for shock arrows by *not* stepping on any of the four cardinal directions when one appears. Stepping on a shock arrows has the same effect on score as not holding a freeze arrow.


Let's run through an example using a 400 step song with 21 freeze/shock arrows.


    Step Score = 1,000,000 / (number of steps + number of freezes and shock arrows)
    Step Score = 1,000,000 / (400 + 21)
    Step Score = 1,000,000 / 421
    Step Score = 2,375.2969...
    Step Score = 2,370 (Rounded down to the nearest 10 points)


This means that the value of each type of step would be (in this case):


    Marvellous = 2,370
    Perfect = 2,360
    Great = 1,410 (rounded down from 1,415.178 from the original step score)
    Good = 460 (rounded down from 465.059 from the original step score)
    O.K. = 2,370
    (anything else) = 0


Remember that the math is performed on the floating point value internally, so it isn't a case of multiplying these resulting values by the number of each step for the final score; calcualtion is always done based on the original step score in this case of (1,000,000/421). Let us run through a quick example comparing the contrast in scoring systems with the previous mix


In the above example of a 400 step song with 21 freeze/shock arrows, assume the following result:

Step Score = 1,000,000 / 421 = 2,375.2969...

Marvellous : 250
Perfect : 100
Great : 45
Good : 5
OK : 20
(1 missed Freeze arrow)

Remember scores are rounded down to the nearest 10 points for display.

The dance level grade is determined based on score alone as opposed to score and difficulty level from previous mixes as shown in the table below.

If an 'AAA' is obtained for getting all perfects or better, underneath the 'AAA' graphic a message of "Perfect Full Combo!" is displayed. Similarily, a full combo with the lowest graded step being "Great" will yield a "Great Full Combo" and a full combo with a "Good" being the lowest graded step will result in a "Good Full Combo". A perfect score of 1,000,000 (All Marvllous steps) earns the title "Marvellous Full Combo!"
