Is there any way a simple section can be added to check how many BPS/BPM you can do and how acurate your streaming is? Like maybe you could generate a stream and test curving and jump rate on it as well. Possibly a streaming scratchpad of sorts.
Hmm.. I guess osu! could generate some sort of average or highest BPM achieved (with perfect accuracy of course). This would be kinda cool to see on your profile.
The DoubleTime BPM should be taken into account since it makes stuff 1.5x faster.
