So recently I discovered https://jaasonw.github.io/osuStreamSpeed.js/, and I've been gauging my stream speed. I get like 170bpm at most for streams, and 100 at most for single taps. What I'm confused about is what bpm means exactly. At least on that site, it seems like the bpm is in quarter notes, but is that the same for in game? Also I hear of people single tapping 200 bpm, or alternating >250bpm. That seems extremely hard to me. Am I just inexperienced or are they measuring it differently than I am?
