I keep seeing people say stuff like "that was a xxx bpm stream" and im just wondering how they know. It cant just be the songs bpm because streams on something like uta feel faster than a similar star rating of songs with higher bpm such as this https://osu.ppy.sh/beatmapsets/1120645#osu/2341604
another example is this https://osu.ppy.sh/beatmapsets/291155#osu/655684 feeling slower than the deceit while having the same bpm
