maimai DX Top Score Analysis

McMai turns your synchronized play records into a top-score summary and offers related views for Best 40, AP results, play count, and friend comparisons. Before querying, update your data and select the correct region.

How to query

1. Update your records using the method for your region.
2. Confirm that CN, JP, or INTL is selected.
3. Send /b50; append #username to view another player when they allow it.

Best 50

Query your Best 50 scores (top 35 old-version charts + top 15 new-version charts).

Command: /b50

Add #username to query another player's data (requires their permission).

Examples:

Command
/b50
/b50 #SomeUser

What the image shows

• Player info and play stats, plus your Rating distribution and grade / combo / sync / DX star breakdowns.
• Rating trend (JP / INTL only): the summary bar shows your Rating over the last 30 days. See /ralog for the full history.
• Chart Affinity: with enough scores, the analysis panel shows a radar of your relative performance across chart types and marks your relative weak spots. See Chart Analysis & Practice. It's hidden when there aren't enough scores; send /practice for calibration charts.

Theoretical B50

Curious how high Rating goes if every chart were maxed? Send /b50 #intlmaxscore for the INTL theoretical B50, /b50 #jpmaxscore for JP, or /b50 #maxscore for CN. These are rebuilt automatically whenever the song database updates.

PK B50

Face off against another player on the charts you've both played and compare Rating.

Command: /pk50 [#username]

• Specify an opponent: /pk50 #Sakura
• No argument: randomly match a player on your server who shares at least 10 played charts with you (only from the current group when sent in a group), preferring players within 100 Rating of you

Examples:

Command	Description
/pk50 #Sakura	PK against Sakura
/pk50	Random match

Rules:

1. Chart set: from the charts you've both played (UTAGE excluded), the two players take turns picking their own highest-RA chart, up to 35 old-version + 15 new-version charts. Each side brings half of the set from its own strengths, so it doesn't matter who starts the PK.
2. Verdict: total Rating on the chart set decides the winner; if tied, the number of charts won decides. Each chart is decided by RA first, then achievement rate if RA is equal.
3. A PK can't start with fewer than 10 shared charts.
4. Cross-server PK: if the two players are on different servers, each chart's constant is taken from JP, then INTL, then CN, in that order.

What the result image shows

• Both nameplates (in-game name frame, dan, and class), the score, and each player's own B50 Rating (for reference only, not used for the verdict).
• A side-by-side comparison of achievement, grade, and RA for every chart, with a per-chart RA difference chart and the chart win tally at the bottom.
• If a player hid their nickname in Profile Display Settings, it's hidden on the image too.
