Timing is also needed in speech, which is quite fast compared to conscious desponse; so the problem with conjunctions might just be that the cerebellum anticipates them. Note that time perception is distorted so that we don't notice how slow conscious response is. So the feeling of "competence" is when your cerebellum is anticipating correctly.
