I have trouble controlling my right hand, the problem comes out a lot in jumpstreams and dense patterns where I just end up tunnel visioning the right side while my left hand is basically on autopilot with no issues at all.
you're still super new to the game. It's a simple reading issue; completely normal. You will get better at controlling your right hand and reading the patterns as a whole as you play more. Practice slower jumpstream maps and play rate packs. Start at a point where you can read the patterns as a whole, and slowly go up.
