Can I find a pattern from this?

Well, the last two nights, I've had one lucid dream each. I found a common pattern in these. I read the day before the first lucid that you are supposed to RC after waking up to make sure that it's not a false awakening. Well, both of my lucids were false awakenings, and I've learned to reality check when I wake up, so I caught both of them. However, there is another similarity. Both of them were between 5:00 and 6:30. Does that mean it would be a good time to try and WILD/ WBTB on the weekends if I got to sleep at the same time as normal? Looking back, I notice that almost all of my lucid dreams have been in the early morning, 5:00 A.M. or later. Is there a reason for this, and can I take advantage of it? I know I sound like a newbie here, but I'm trying to figure out if I can use this new information to get more LD's. Hopefully I'll have an LD for the third night in a row tonight.
