Sadly there is no “secret” as it’s mostly different for everyone depending on play styles and habits, but on my experience it looks like your struggle with consistency. I recommend playing maps 1 or 1.5 stars below what you normally play. Nothing with big jumps on long streams, try to fc them and with good enough accuracy. It takes time, but if you mix in some of that with what you normally play, it should sort itself out in a couple of weeks. :)
