ONGEKI:Rating

Rating is a number that shows the technical skill of a player, like in CHUNITHM and maimai.

Chart rating

Per-chart rating value is based on internal level and Technical Score. It is calculated as follows, using truncation:

$ChartRating=max(InternalLevel+trunc(ScoreCoefficient,2),0)$

Score coefficient is calculated linearly between:

• 900,000: -4.0
• 970,000: +0.0
• 1,000,000: +1.5
• 1,007,500: +2.0

Therefore, starting from S, it increases by 0.01 every 200 points until SSS and then every 150 points until SSS+, where it reaches the highest possible value. Below S, it decreases by 0.01 every 175 points.

Profile rating

$ProfileRating=trunc\left({\frac {OldBest30+NewBest15+Recent10}{55}},2\right)$

LUNATIC 0 charts and Bonus Tracks are excluded.
