Do not manually edit anything in an .osu file that cannot be changed through the Editor. The only exceptions are .osu-specific storyboards, slider velocity multipliers and skin-related options such as SliderBorder and SliderTrackOverride. If non-standard slider velocity multipliers are used, they must be announced in the beatmap description during the modding process.So as far as I know, the slider velocity only goes down to 0.5x without some sort of manual editing. However, I've been modding a LOT of maps that DON'T adhere to this, but there's no notation of it within the beatmap thread that I've seen.
Does this rule still exist? I feel like it's never talked about and it's never really seen as something important to have, so I'm wondering if this little clause even needs to be in the ranking criteria as a rule. Or on the flip side of things, if the community needs to be reminded of the rules regarding these non-standard slider velocities.
EDIT: Since I apparently didn't clarify, I'm talking about the last clause that states
