It's weird I know, but I was able to S 4.5* and 5*, some of the newer beatmaps that are the same difficulty are for some reason harder than what I am used to. The same goes with lower rated once. They mostly have patterns that I only found on 5* maps.. It's really frustrating, since I think I can beat 5* while I can't even beat 4.2* because the patterns are that hard.
