i can't seem to do patterns like chordjack, vibro, stream etc. as fast as my right hand does, and it really bothers me. i just came back from a 1 month break, and this is the first problem i'm running into. any tips on recovering my left hand's speed? for reference, i could play 6,5*+ chordjack maps no problems with my left hand, and now it can't keep up with 5* maps
