I can play songs at 4.5 pretty easily, but the moment I try to play something higher, ie. a 4.7 or 4.8, I can't even pass them. I feel as if my fingers can hit the notes, but I'm having a hard time reading things consistently. Some days I'll read around a 5 star, others I can barely read a 4.3. Any tips on improving reading to be more consistent?
