The way I see it is that expectation has very little to do with actually gaining lucidity. Lucidity means being aware, applying desire and forced expectation is far from honest open awareness.

Ryan Hurd developed a technique to specifically take advantage of this phenomena though. It's as simple as purposely taking off a week or two every month and let things stew. (the subconscious sure is a picky consumer) and continuing your practice (whatever it may be) the rest of the month. This makes a lot of sense for me because I can't purposely decide to learn something non-chalantly, I'm a violent student XD
