Notes are judged based on how far from the input is from exact time of the note.
|PERFECT:||within 12.5 ms|
|GREAT:||within 25 ms|
|GOOD:||within 50 ms|
|HIT:||within 100 ms|
|MISS:||more than 100 ms|
Tap notes judgments have the following score weights:
Rhythm Horizon uses an algorithm to assign difficulty numbers to charts. The algorithm is based on physical movement required to pass charts on with the Rhythm Horizon life system. It does not consider the difficulty of reading, or the difficulty of timing a chart. The algorithm includes a full analysis of patterns and note distribution in the chart.
Scores are ranked on a per-chart bases. Rankings are based on percent score. Ties are broken by minimum life, then by average timing error, and finally by date/time of the score.
The term mashing refers to hitting inputs in a way that does not correspond precisely with notes in the chart. Rhythm Horizon uses an algorithm to ignore some judgements which it considers to be mashed. Specifically, if the inputs that trigger two notes are much closer in time than the notes are, one of the inputs will be ignored. This is intended to avoid penalizing players for unintentionally hitting multiple notes at the same time, as well as reduce some of the benefit of intentionally mashing.
