The more you RC during the day the more beneficial it is to you. If you want results quickly, I recommend looking into all day awareness. Otherwise, try doing about 20 a day to start out. You have to pay attention to what you're doing though, don't just RC as an impulse, really be aware of reality and pay attention to detail.

Couple this with a dream journal to boost your recall and you should be having DILDs in no time.
