Internal combo cap is 999999, though the max combo displayed is 9999. Score cap will be hit before combo cap anyway. | |||
==== Extreme US Endless ==== | |||
According to my notes, the same system is used in Extreme US and its derivatives, along with SuperNOVA and SuperNOVA2. None of this has been fully verified, though. | |||
What we have: | |||
If Good or lower, Step Score = 0. Otherwise: | |||
If C <= 10000, | |||
:Step Score = int((C^2 + B*C + B*D + C*D)/1000) | |||
If C > 10000, | |||
:Step Score = floor((step score at C = 10000) + (C-10000)*(10 + D/1000)) | |||
where: | |||
* N = steps plus freezes in song | |||
* D = ??00 if on Beginner, 1000 if on Basic, 1200 if on Difficult, 1400 if on Expert, ??00 if on Challenge. | |||
* C = combo after (?) step | |||
* B = floor(100000000 / N) | |||
* J = 5 if Marvelous or OK, 4 if Perfect, 3 if Great | |||
What we need: | |||
* How does J affect the score? It's not a straight multiplier, but on low combo and state counts it's close | |||
* Rounding | |||
* Values of D | |||
==== X Endless ==== | |||
Not fully verified. | |||
Let: | |||
* N be the total number of notes hit so far. (how do we define a "hit", clarify) | |||
* M be the total number of Marvelouses so far. | |||
* N' = N - P, where | |||
** P is a penalty defined as follows: Every time a combo-breaking judgement occurs, floor(C/4) is added to P, where C is the stage combo before the note (i.e. the current combo, but only counted from the start of the stage if it began in a previous stage). | |||
* S = current stage number. | |||
* L = 2*S^3 if on Level 1, and floor(S^3/D) + 1 otherwise, where | |||
** D = 3 if on Level 2, 6 if on Level 3, 8 if on Level 4 and 10 if on All. | |||
Then the step score is: | |||
* Marvelous: 3 * (N' + M) * L | |||
* Perfect/OK: 2 * N' * L | |||
* Great: N' * L | |||
There may be rounding errors involved. | |||
Strictly speaking, the formula for L is actually 2*min(S^3,2^31 - 1) for Level 1 and floor(min(S,1600)^3/D)+1 for other levels, but the caps aren't expected to be reached before the score cap (10^16 - 1). | |||
