I must say that RCs are quite useful during dreams with minimum awareness. Such tiny speck of awareness will grant you at most one single action. What will you do? Think about the scenery around you? Try to analyze the behavior of people around you? There's simply not enough awareness to do that! And if you try, you are very likely to be carried away thinking about "fake" relationships, events and other aspects of the dream you are experiencing. Really, analyzing the dream without first being lucid is not the best idea, as dreams are very tricky. Back to the question: what do you do with that tiny speck of awareness? You look at a digital clock, read a single word over or check that number plate on a car in front of you. Something looks funky? Bam! You are lucid. This is how a simple RC makes you lucid.

I'm not speaking against your model, as you are on the right track. Such thinking indeed produces really cool results. I dont know if it had any effect on my LDs, as I wasnt having many LDs when I was trying something like what you are suggesting. However I had a lot of very cool trippy experiences on the borderline between waking and dreaming. I must say that only increased awareness allowed me to experience them.
