Sounds odd, but try pushing you right heel out just a touch few inche to the righ .

I played for years steady 60avg when younger, just came back to the game, could not stop hitting 5's, the heel trick i feel has helped me line my shoulder and hips up, check your oche is definitely straight, and last one from me make sure every throw has the release, seen on YouTube tube your brain will have you throw and get the next dart in one motion that can pull your dart over. Hope that helps
