Hi! I believe the current BPM scaling guidelines are too vague, and never enforced. I aim propose reasonable, enforceable BPM scaling rules/guidelines for speedcore beatmaps. I propose these be added to a separate paged linked to in the taiko ranking criteria so that the taiko ranking criteria doesn't get bloated.
Kantan:
Rules:
Patterns on snaps faster than 1/1 are disallowed. These patterns are too complex for beginner players.
Guidelines:
1/1 patterns should not be longer than five notes. Anything longer is likely to be too straining for beginners. Patterns like these should be followed by a rest moment.
Base Slider Velocity should be lowered to 1.2 or lower. The default speed is likely to be too fast for beginners.
Futsuu:
Rules:
Patterns on snaps faster than 1/2 are disallowed. These patterns are too complex for beginner players.
Guidelines:
1/2 patterns should not be longer than five notes. Anything longer is likely to be too straining for beginners.

Rules:
Patterns on snaps faster than 1/4 are disallowed. These patterns are too complex for the target audience of this difficulty level.
Guidelines:
1/4 patterns should not be longer than three notes. Anything longer is likely to be too straining for the target audience.

Rules:
Patterns on snaps faster than 1/1 are disallowed. These patterns are too complex for beginner players.
Guidelines:
1/1 patterns should not be longer than three notes. Anything longer is likely to be too straining for beginners. Patterns like these should be followed by a rest moment.
Base Slider Velocity should be lowered to 1.0 or lower. The default speed is likely to be too fast for beginners.
At least 1 rest moment that is 4/1 or longer should be inserted after 16/1 to 20/1 of continuous mapping. Using rest moments less frequently is acceptable if either the pace of the music makes rest moments counter-intuitive or if the continuously mapped part is overall more forgiving to the player.

Guidelines:
1/2 patterns should not be longer than three notes. Anything longer is likely to be too straining for beginners.
Base Slider Velocity should be lowered to 1.2 or lower. The default speed is likely to be too fast for beginners.
At least 1 rest moment that is 3/1 or longer should be inserted after 16/1 to 20/1 of continuous mapping. Using rest moments less frequently is acceptable if either the pace of the music makes rest moments counter-intuitive or if the continuously mapped part is overall more forgiving to the player.
Muzukashii:
Rules:
Patterns on snaps faster than 1/4 are disallowed. These patterns are too complex for the target audience of this difficulty level.
Guidelines:
1/4 patterns should not be longer than three notes. Anything longer is likely to be too straining for the target audience. They should consist of one colour change at most which should take place at the start or the end of the pattern.
At least 1 rest moment that is 2/1 or longer should be inserted after 16/1 to 20/1 of continuous mapping. Using rest moments less frequently is acceptable if either the pace of the music makes rest moments counter-intuitive or if the continuously mapped part is overall more forgiving to the player.

Guidelines:
At least 1 rest moment that is 3/2 or longer should be inserted after 16/1 to 20/1 of continuous mapping. Using rest moments less frequently is acceptable if either the pace of the music makes rest moments counter-intuitive or if the continuously mapped part is overall more forgiving to the player.
Kantan:
Rules:
If a 1/1 pattern is used, the patterns must stay simplistic and be followed by a rest moment. Finisher notes must not be used in patterns as such.
Patterns on snaps faster than 1/1 are disallowed. These patterns are too complex for beginner players.
Guidelines:
2/1 patterns should not be longer than seven notes. Anything longer is likely to be too straining for beginners. Patterns like these should be followed by a rest moment.
Base Slider Velocity should be lowered to 0.8 or lower. The default speed is likely to be too fast for beginners.
At least 1 rest moment that is 4/1 or longer should be inserted after 16/1 to 20/1 of continuous mapping. Using rest moments less frequently is acceptable if either the pace of the music makes rest moments counter-intuitive or if the continuously mapped part is overall more forgiving to the player.

At least 1 rest moment that is 3/1 or longer should be inserted after 16/1 to 20/1 of continuous mapping. Using rest moments less frequently is acceptable if either the pace of the music makes rest moments counter-intuitive or if the continuously mapped part is overall more forgiving to the player.
Muzukashii:
Rules:
Patterns on snaps faster than 1/2 are disallowed. These patterns are too complex for the target audience of this difficulty level. For songs that follow a swing beat, this limit is 1/3.
Guidelines:
1/2 patterns should not be longer than five notes. Anything longer is likely to be too straining for the target audience.
At least 1 rest moment that is 2/1 or longer should be inserted after 16/1 to 20/1 of continuous mapping. Using rest moments less frequently is acceptable if either the pace of the music makes rest moments counter-intuitive or if the continuously mapped part is overall more forgiving to the player.
1/2 patterns with one or more colour changes should be used sparingly. They should be avoided in conjunction with other patterns of this nature because the target audience of this difficulty level is not used to patterns of this complexity.
1/2 patterns which are longer than three notes should consist of one colour change at most which should take place at the start or the end of the pattern. Patterns more complex than that would be too demanding for intermediate players. These patterns should be followed by a rest moment.
Oni:
Rules:
Patterns on snaps faster than 1/4 are disallowed. These patterns are too complex for the target audience of this difficulty level.
Finisher notes must not be used in any 1/4 patterns or faster in this difficulty. The finisher usage on these patterns is too complicated for the audience at this level.
Guidelines:
At least 1 rest moment that is 3/2 or longer should be inserted after 16/1 to 20/1 of continuous mapping. Using rest moments less frequently is acceptable if either the pace of the music makes rest moments counter-intuitive or if the continuously mapped part is overall more forgiving to the player.
1/4 patterns should not be longer than five notes. Anything longer is likely to be too straining for intermediate players.
1/4 patterns which are longer than three notes should consist of one colour change at most which should take place at the start or the end of the pattern. Patterns more complex than that would be too demanding for the target audience. These patterns should be followed by a rest moment.
