i think its fine cuz as u said they are rather far apart and im pretty sure new players can still read the difference in AR between a 1/2 stack and 1/1 stack
also i used a single combo for 1/2 stacks and NCed the second note of 1/1 stacks so theres Some visual distinction outside reading AR
i get u but i think half the diffs also did the same thing as me so i think it's not That bad and i cant really find a good way to pattern it anyway unless u think of a cool way
