Q1. What is GrooveTrack
A1. GrooveTrack is the sister site to DD:Recall. It's the same thing as DD:Recall except that instead submitting DDR scores, you're submitting ITG scores. There are some minor differences to the interface that reflect the difference between ITG and DDR.
Q2. What is "Raw Percent"
A2. GrooveTrack is different from DD:Recall in that it allows you to enter simple percentages in place of other score data. When you enter a raw percent value, this ill override any DP calculations (DP is calculated either from raw DP or the rating fields). When raw percent scores are entered, the DP count will appear as "???" on score lists.
Q3. How does GrooveTrack calculate my score percent?
A3. GrooveTrack uses an algorithm that mimics In The Groove. For songs, scores are entered subtractively so the remaining taps are implicitly fantastic. Whereas courses require fantastics to be entered manually. So for songs, the formula looks something like this:
((chart taps + chart holds + chart rolls) * 5) - (score_excellents) - score_greats * 3 - score_decents *5 - score_wayoffs * 11 - score_misses * 17 - ((chart_holds + chart_rolls) - score_yeahs) * 5 - (chart_mines - score_mines) * 6
For courses, the formula is a little simpler:
(score_fantastics + score_yeahs) * 5 + score_excellents * 4 + score_greats * 2 + score_decents * -6 + score_misses * -12 + (chart_mines - score_mines) * -6
Internally, you start out with a DP score of zero and as you hit steps, you're score is affected according to the judgements you receive. The following list shows how each judgement is weighed:
Fantastic: +5
Excellent: +4
Great: +2
Decent: 0
Way Off: -6
Miss: -12
Yeah (Hold/Roll held): +5
Bad (Hold/Roll lost): 0
Mine hit: -6
Mine avoided: 0
Q4. Why does GrooveTrack get my percentage wrong?
A4. It doesn't. You probably got an incorrect percentage, either from one of the many ITG2 cabinets that have the infamous scoring bug or from ITGFreak's percentage calculator, which doesn't round decimals correctly (at the time of writing 12/22/05).
