Adding on to arcade sandwhich comment, these stream maps usually consist heavily of low spacing consecutive notes that represent the rhythm in background rather than the melody itself. We don’t really consider it overcharted since these maps mainly revolve around tapping and a bit of aim (relative to overall gameplay). As a result, these patterns aren’t recognised as individual circles but more so as long segments. Which is why they hold the same weight as something which may follow the melody, have larger spacing but slower speed.
