The formula for calculating the score for a combo is a bit complicated, the point value for any step in a combo depends on two factors :
• Perfects are worth 3 times as much as Greats.
• The point value for a step increases every time the combo increases by 4.

The exact formula for the score of a combo is...
let [x] denote the greatest integer function (i.e., where [x] is the greatest integer less than or equal to x). Then, the point value for the nth step in a combo is :
S(n) = G(n) if the nth step is a Great, or P(n) if the nth step is a Perfect;
G(n) = 100 ([n/4]^2 + 1);
P(n) = 3G(n);
