I've already pointed this out in Ranking Criteria, but I realized preventing actual problem by rule is somewhat stupid. So, what's the problem: Notes in taiko change volume depending on the time you click it, so if there is timing point with volume change exactly on the note and you click it even 1ms earlier, it will use volume of previous timing section. I think it would be less misleading and logical if notes had forced volume depending on the section they are in, not on whether you click it early or late. As long as you hit the note, either early or late, it should use volume that was set by timing/inherited points.
