A great review of techniques! I've been doing RCs for 3 to 7 times a day (not enough I know!) for the past couple of months. I hadn't made a single RC in a dream, with the exception of once when I was flying. However, the number of lucid dreams had increased from 1-2 a month to 4-5 a month. My plan is to repeat my dream signs till I finally become lucid upon encountering them, not just by chance. I also find DEILD a good technique to practice as I really do wake a number of times during the night and it is somewhat less demanding than WILD.
