So a week ago i was able to consequently stream 180 bpm and this week i can barrely keep 160, i can do 180 but i freeze on some point during the stream and i cant press the keys at the same speed.. However,the weekend i played so much osu and all of a sudden, i couldn't stream this from monday, usually my pointing finger doesn't want to obey and begins tapping the air. I remember one analogic situation, a game that also required quite fast tapping, i played it for about 2-3years and the same exact thing happened, i took a huge break, 4months, and i still couldnt tap as well as i could. Has anyone experienced something like this or know what's wrong and how should i treat this? This really worries me :<
