I have the same problem.
The solution: practice easy maps. I've been playing hards and long AR8 insane maps everyday, as well as AR9 insane, and I retry every time I miss (unless it was from a stream, I suck at those...). So I've been training my self to read every note properly and not to miss. Don't play maps that are too fast and you have to spam through.
It's been working so far, but consistence isn't something you can develop overnight. I think it takes a lot of frustration and retries on long slow maps.
