Grading and Score
Grades: AAA Perfect! - AAA - AA - A - B - C - D - E
For those who don't care about the exact formula for calculating the score of a combo, it will suffice to say that Perfects are worth just a little more than Greats, and that steps are worth more as your combo increases, but not nearly as much as it did in the first US mix.

For those who do care, let n be the number of the step in the combo. Then, the point value for the nth step is:

S(n) = G(n) if the step is a Great step, and P(n) is the step is a Perfect step;
G(n) = 555 + 333n;
P(n) = 777 + 333n;

Therefore, the total point value for a combo of n steps is the summation of S(n) from 1 to n. I must thank EnoOn for telling me how the scoring system for DDR USA worked. I don't think I would have had the patience to figure this out myself.
