Finisher notes for 1/4 patterns in this difficulty must only be used at the end of that pattern. Placements other than this can disturb the readability for the audience at this level.
tl;dr change this rule to a guideline.
This would be a great guideline, and is a too restrictive rule. Allowing it to be a guideline gives the leniency when it's appropriate and literally everyone with a small portion of sense for this game and its mechanics will understand it doesn't make sense for low BPM tracks - being around 140 - to follow something that is obviously made for average to high BPM tracks. I'm very sure that nominators are responsible-minded to understand when it's correct to give this regulation an exception and when not.
beatmapsets/1140186 in the Oni difficulty at 00:43:823 (178,179) - is clearly playable for an Oni difficulty.
Yes, I have made this proposal in reaction to a mod to my map that refers to this rule but the idea to have this regulation as a rule is too much and unflexible.
