It's a good progression but you are still really bad at the game (so am I). Dont do the rookie mistake (I did it), to only care about rank and push yourself and the star rating at your maximum only for PP.
When I start the game I was like "Wow people ranked around 150k play sooo well". So I rush as a retard to get to this level.
And know I finally understand that being stuck on high 4* make me a total piece of sh*t. :c
I'm full of bad habit, I can't acc, I have a bad tapping, a terrible finger control and I'm currently learning the game on 3*. It's super infuriating. And I have no fun playing the game.
But I need to do this to progress again. So if you dont want to do the same mistake that I did, try to master the low 4 stars with an acc above 97%!
