maimai DX:Rating

Rating, officially DX Rating (でらっくす RATING), is a number that shows the skill of a player, similar to jubility in jubeat, Volforce in SOUND VOLTEX, etc.

A major difference with the pre-DX Rating is that, rating for charts is now determined by highest score only. The "recent" slot (as it was called colloquially) in the old Rating system, that measures a certain number of recent playthroughs, is gone. This means that the Rating does not decrease unless your 段位 drops.

General Information

The exact Rating values for each chart is now viewable with the Standard Course subscription. This makes it possible to deduce the formula used to calculate the per-chart Rating: Internal level * rank constant * achievement rate, rounding down.

• Internal level is a number with one decimal place that is not shown in gameplay. BASIC charts are always level X.0; ADVANCED and above can have other values. For level 7 and above, X.7 ~ X.9 corresponds to level X+, and X.0 ~ X.6 corresponds to level X.
• Rank constant can change between versions.
• Achievement rate is capped at 100.5%; higher rates are treated as 100.5% for rating calculation purposes.

maimai でらっくす Splash

No change from maimai でらっくす PLUS.

maimai でらっくす Splash PLUS

段位 rating is no longer a part of the total rating. Friend Versus now awards class emblems instead of 段位 (basically just a name change).

(Unknown: how is the number of charts used for the rating calculation changed? FC2 wiki says the top 50 charts are used, without specifying the number for new charts and old charts separately)

Rank constant is also changed significantly:

• (lower ranks unknown)
• A: 13.6
• AA: 15.2
• AAA: 16.8
• S: 20.0
• S+: 20.3
• SS: 20.8
• SS+: 21.1
• SSS: 21.6
• SSS+: 22.4

Color for ratings is also changed:

Platinum	–	14500～14999
Gold	8000～8499	14000～14499

Purple	5000～5999	10000～11999
Red	4000～4999	7000～9999
