This this this!
oh shit time for some more shitposts
try switching the BPM around constantly might work
or just focus on getting good acc on low BPM stuffs after that I guess
SSing streams is the only thing I'm good at and you have to change the BPM frequently. Just think about it like this, once you can stream 200 BPM, 170 will feel slow and you will need better finger control in order to get good accuracy.
Also, practicing high BPM burststream maps won't help you with long streams.
edit: tl:dr: play sub 150 BPM stream maps, I may post some if you need them.
