== Grading systems == | |||
=== 1st === | |||
Derived by me, not yet checked on AC. | |||
Possible grades are S, A, B, C, D. | |||
* If (bad + miss) == 0 and (max combo >= 100 or perfects >= 0.75 * total steps) then S. | |||
* Otherwise: | |||
** Set provisional grade to A if (max combo >= 50 or perfects >= 0.5 * total steps) and B otherwise | |||
** Deduct one grade if (bad + miss) > 0.05 * total steps | |||
** Deduct another grade if (bad + miss) > 0.15 * total steps. | |||
=== 2nd === | |||
Found on AIJ. | |||
Possible grades are SS, S, A, B, C, D. | |||
Let S be the total number of steps and C be the max combo. Define the following thresholds: | |||
* C_1 = min( 0.9 * S, 100) | |||
* C_2 = min( 0.5 * S, 60) | |||
* C_3 = min( 0.5 * S, 20) | |||
Let: | |||
* GP = (C == S) + (C >= C_1) + (C >= C_2) + (C >= C_3) | |||
** i.e. if C == S then GP = 4, else if C >= C_1, GP = 3, etc. | |||
* MT = 4 - GP. | |||
Then: | |||
* Provisional grade is SS if GP == 4, S if GP == 3, A if GP == 2, B if GP == 1, C if GP == 0. | |||
* Deduct one grade if either (misses > MT) or (perfects < greats). | |||
=== 3rd === | |||
Possible grades are SSS, SS, S, A, B, C, D, E. | |||
Assign DP per judgement: | |||
* 2 for Perfect | |||
* 1 for Great | |||
* 0 for Good | |||
* -4 for Boo | |||
* -5 for Miss | |||
Then: | |||
* If failed (empty life bar at some point), assign E. | |||
* If all Perfects, assign SSS. | |||
* Else, if all Great or Perfects, assign SS if (perfects >= 0.8 * total steps) and S otherwise. | |||
* Else, check DP / Max DP: | |||
** If >= 0.8, assign A | |||
** If >= 0.64, assign B | |||
** If >= 0.5, assign C | |||
** Else, assign D. | |||
=== 4th === | |||
Possible grades are AA, A, B, C, D. | |||
Assign DP per judgement as in 3rd. | |||
Then: | |||
* If failed (empty life bar at some point), assign D. | |||
* If all Perfects, assign AA. | |||
* Else, if all Great or Perfects, assign A. | |||
* Else, check DP / Max DP: | |||
** If >= 0.64, assign B | |||
** Else, assign C. | |||
=== 5th === | |||
Possible grades are AAA, AA, A, B, C, D, E. Very similar to 3rd. | |||
Assign DP per judgement as in 3rd. | |||
Then: | |||
* If failed (empty life bar at some point), assign E. | |||
* If all Perfects, assign AAA. | |||
* Else, if all Great or Perfects, assign AA. | |||
* Else, check DP / Max DP: | |||
** If >= 0.8, assign A | |||
** If >= 0.64, assign B | |||
** If >= 0.5, assign C | |||
** Else, assign D. | |||
Note that A, B, C and D are the same as 3rd's A, B, C and D. | |||
=== MAX to Extreme === | |||
Possible grades are AAA, AA, A, B, C, D, E. | |||
Assign DP per judgement: | |||
* 2 for Perfect | |||
* 1 for Great | |||
* 0 for Good | |||
* -4 for Boo | |||
* -8 for Miss | |||
* 6 for OK | |||
* 0 for NG | |||
Then: | |||
* If failed (empty life bar at some point), assign E. | |||
* Else, check DP / Max DP: | |||
** If DP = max DP, assign AAA | |||
** If >= 0.93, assign AA | |||
** If >= 0.80, assign A | |||
** If >= 0.65, assign B | |||
** If >= 0.45, assign C | |||
** Else, assign D. | |||
