I still do this occasionally when I do I slow it WAY down till it's right. It's just muscle memory. Maybe try Metro dome slow enough till you get it right every time then bring the speed up slowly. If you do it too fast a bunch a times wrong it will normally not become right until u slow it down and learn it right.
