well it is up to you how you want to play either purely for fun or have some competition involved, since your recent activity shows you investing your playcounts retrying easier maps
you are doing alright but need to step up the difficulty if you want to improve in the game
All the hards that I have FC'd include Chaosmaid (hardmaid)(ranked 1000/5000), Levaslater - NNRT (Hyper)(ranked 1500/4000),Groove Coverage Holy Virgin (hard)(ranked 5900/13000), Haruka na Sora (hard) (ranked 560/1600), Tewi Ma Park Endless Park (hard)(1860/6000) and I have a few others.
I also get 92%+ for a lot of hards that I can't FC or be bothered to replay 100 times.
Hope that clears your mind up a bit you baka
