About Mov Level

What is Mov Level?

• Mov Level (commonly known as "Mov") is a guideline separate from the difficulty level, established to represent the unique finger-moving and Alternative (Alt) elements inherent in 11key/11Lkey modes.
• It does not depend on the note density of the charts.
• It is notationally combined with a movement component (alphabet) and a modifier component (symbol), such as "C↑" or "D -".

Component	Overview
Movement Component	Difficulty based on finger-moving. Expressed in 7 tiers from A to G. Instead of the average difficulty, it is based on the finger-moving required in the most difficult sections, including local bursts. Expressed in 7 tiers from A to G.
Modifier Component	Modifies the movement component level by considering Alt elements, the difficulty of transitions, and potential end-game difficulty spikes (last-gasp sections). Expressed in 5 tiers: "↓", "－", "(None / Blank)", "＋", and "↑".

Alt Level

• Used as an indicator to measure Alt elements rather than pure movement.
• While Mov measures movement difficulty, Alt measures the difficulty of reading/interpreting the notes.
• There are two types, Primary (主) and Secondary (副), but the criteria remain the same; they only differ in their target areas.

Target	Overview
Alt Level (Primary)	The main Alt element. In 11key, this refers to SDF and the arrow keys; in 11Lkey, it refers to the arrow keys and JKL.
Alt Level (Secondary)	Alt elements other than those mentioned above. It refers to Alts used in irregular cases such as left-hand movement. In 11key, this refers to JKL and the arrow keys; in 11Lkey, it refers to the arrow keys and SDF. *Note: For 11Lkey, the Alt difficulty during right-hand movement is applied due to the Vertical Level criteria below.

Alt Level	Overview
Level 0	No Alt elements present.
Level 1	Alt is used at the timing of finger-moving. Used occasionally/sporadically.
Level 2	Used when timings are relatively aligned, such as in unisons, symmetries, rolls (trills), or instances where one hand maintains a constant rhythm (mainly 4th notes) while the other plays the main melody.
Level 3	Used when irregular interactions occur, such as irregular chords (mainly 8th notes). In 11Lkey only, this also applies to Level 2 patterns that are particularly difficult to read.
Level 4	Anything that exceeds Level 3.

Vertical Level

• A tier system applied to irregular left-hand movement (the combination of 5key and left 7key) in 11Lkey mode. Commonly known as 2D layout.
• This is set up because, in 11Lkey, players can sometimes handle notes with the left hand without having to move the right hand.
• It takes into account playability (and partially readability).

Vertical Level	Overview
Level 0	No simultaneous chords involving 5key and left 7key.
Level 1	Used occasionally/sporadically. ※
Level 2	Used in regular repetitions (mainly 4th notes). ※
Level 3	Used in irregular chords (mainly 4th and 8th notes). ※ Patterns where the difficulty increases due to consecutive combinations fall into this level.
Level 4	Anything that exceeds Level 3.

※ If simultaneous chords involving SW / DE / FR / 3 interactions are present, the level increases by 1. (Example: A regular repetition pattern (Level 2) that includes SW / DE / FR / 3 interactions ⇒ Level 3)

Mov Level Rating Criteria

• These are the rating standards used in Cross Walker. The Alt Level and Vertical Level described above are used in conjunction.
• The 4th and 8th notes mentioned in the tables are based on a reference speed of approximately BPM 160.
• The rating criteria for 11W and 17key modes are basically identical to 11Lkey.

≫ Movement Component

(For 11Lkey, the baseline is set slightly higher overall due to the key layout)

11key

Mov	AltLv.(Pri)	AltLv.(Sec)	Cross	Overview
A	0 (～1)	－	－	Consistently separates the 5key and 7key sections intentionally (per section). Sufficient leeway (half a measure or more) is provided for movement. Used more as a combination of 5key and 7key rather than distinct 11key functionality.
B	1 (～2)	－	－	Shorter movement intervals than A (every 1 to several measures). No consecutive transitions. Applies if the right hand moves independently within an A-tier structure (direct transitions between arrow keys ⇔ JKL without intervening SDF notes).
C	2 (～3)	－	－	Movement centered around 4th notes, which can occasionally result in consecutive transitions. The timing of the movement is mostly regular.
D	3 (～4)	－	－	Movement centered around 4th notes. The frequency of movement is higher than C, easily resulting in consecutive transitions. Sudden or unexpected movements are significantly more prominent than in C.
E	0～4	0～1	－	Accompanied by sporadic left-hand movement (continuing over several measures). (Guaranteed E-tier once left-hand movement is required) Even if the above is not included, charts with movement centered around 8th notes fall under E.
F	3～4	2～3	Beg/Int	Accompanied by irregular right-hand movement or cross movement. (Guaranteed F-tier once irregular right-hand or cross movement is required) Alternatively, left-hand movement states persist for several measures, which can lead to consecutive transitions blending both left and right-hand movements. The 7key section may also be handled by the left hand. ※ Irregular right-hand movement... A finger-moving style where instead of moving in blocks like JKL or arrow keys, the player handles notes by hitting L and Right, or K and Up with the same hand. (Example: "Watchdog" / by izkdic)
G	4	4	Adv	All charts that exceed the F-tier criteria. Features so-called "freedom" movement, requiring flexible adaptation based on the situation.

11Lkey

Mov	AltLv.(Pri)	AltLv.(Sec)	Vertical Lv.	Overview
A	0 (～1)	－	－	Consistently separates the 5key and 7key sections intentionally (every 1 to several measures). Sufficient leeway (half a measure or more) is provided for movement. Used more as a combination of 5key and 7key rather than distinct 11Lkey functionality.
B	1 (～2)	－	－	Movement centered around 2nd to 4th notes, with occasional consecutive transitions. Guaranteed B-tier if the left hand moves independently within an A-tier structure (direct transitions between arrow keys ⇔ SDF without intervening JKL notes).
C	2 (～3)	－	0 (～1)	Consecutive transitions and movement centered around 4th to 8th notes (including partial 16th notes). Movement patterns are mostly regular. May include vertical chords (Guaranteed C-tier once vertical chords are required).
D	3 (～4)	－	0 (～1)	Consecutive transitions and movement centered around 8th notes (including partial 16th notes). More irregular than C, with many sudden or unexpected movements. Vertical chords are limited and mostly playable within the natural flow.
E	2～4	－	1～2	Movement centered around 8th to 16th notes. Imposes a heavy burden on the left hand. Frequently features layouts containing vertical chords where right-hand movement is not required.
F	2～4	0～2	3	Accompanied by right-hand movement, or complex vertical movement even when right-hand movement is absent. (Guaranteed F-tier once right-hand movement is required)
G	4	3～4	4	All charts that exceed the F-tier criteria. Features so-called "freedom" movement, requiring flexible adaptation based on the situation.

≫ Modifier Component

(Common to both 11key and 11Lkey)

• Modifiers such as "↓" or "－" do not exist for Mov:A, and "＋" or "↑" do not exist for Mov:G (as they represent the lower and upper limits, respectively).
• If a chart has a local difficulty spike (－) but features a highly intense Alt element (＋), the modifiers may cancel each other out (resulting in no modifier / blank).

Symbol	Pronunciation	11 / 11L key Criteria
↑	Up (2-step plus)	Applied when the combined Alt Level / Vertical Level is 2 or more steps higher. Or when the chart is significantly harder to read (relative to its Mov) due to Alt relations, AND the Alt Level / Vertical Level is 1 step higher.
＋	Plus (1-step plus)	Applied when the Alt Level / Vertical Level is 1 step higher. Or when the chart is harder to read (relative to its Mov) due to Alt relations. If multiple conditions for a Mov tier are met, it results in a "＋" or higher.
	None (Blank)	No modification. Indicates that the Alt intensity is standard for that movement component level.
－	Minus (1-step minus)	Applied when the baseline Mov level is 1 step lower, excluding local difficulty spikes (accounting for roughly 1/8 or less of the entire chart). Or when the Alt Level / Vertical Level is 1 step lower. Often assigned when the Mov temporarily spikes due to a local burst or a last-gasp section.
↓	Down (2-step minus)	Applied when the baseline Mov level is 2 or more steps lower, excluding local difficulty spikes (accounting for roughly 1/8 or less of the entire chart). Or when the combined Alt Level / Vertical Level is 2 or more steps lower. Commonly used when left-hand movement is required locally (Mov:E) but the rest of the chart sits at a Mov:B tier.

(This is a conceptual mapping and may not always apply exactly as shown)

Movement	1	2	3	4	5	6	7

Matrix Description

• As demonstrated by this matrix, a chart rated "B↑" is not necessarily easier than one rated "C↓".
• In terms of local movement intensity, "C↓" is more demanding; however, in terms of secondary factors like Alt elements, "B↑" presents a greater challenge.
• The modifier components scale relative to the movement components because Alt demands naturally intensify as the amount of movement increases.
