Well, it is kinda hard to determine exactly how long and when your REM cycles start. First of all REM cycles are about every 90 minutes which for the most part your data shows is true. However, throughout the night your REM cycles will gradually increase maybe a few minutes to ten minutes in length and will begin before this "90 minute cycle." When you are really tired/sleep deprived you can enter REM almost immediately so you have to have a standard sleep schedule that is consistent fora while as well as a daily schedule that is not out of the ordinary.
Take a look at this to aid in your decisions:

As between 11 and 2:30 you may have had a couple stages of REM and not have woken up so it is hard to say. After all, you do wake up many times during the night and don't remember because your brain is still writing to "dream memory." I've never had the ability to do what you did with this sleep schedule and wake up naturally so congrats.
“Studies show that the length of sleep is not what causes us to be refreshed upon waking. The key factor is the number of complete sleep cycles we enjoy. Each sleep cycle contains five distinct phases, which exhibit different brain- wave patterns. For our purposes, it suffices to say that one sleep cycle lasts an average of 90 minutes: 65 minutes of normal, or non-REM (rapid eye movement), sleep; 20 minutes of REM sleep (in which we dream); and a final 5 minutes of non-REM sleep. The REM sleep phases are shorter during earlier cycles (less than 20 minutes) and longer during later ones (more than 20 minutes). If we were to sleep completely naturally, with no alarm clocks or other sleep disturbances, we would wake up, on the average, after a multiple of 90 minutes–for example, after 4 1/2 hours, 6 hours, 7 1/2 hours, or 9 hours, but not after 7 or 8 hours, which are not multiples of 90 minutes."

To me it seems that you had about 5 sleep cycles, maybe 6. Personally I take advantage of the longer sleep cycles and REM toward the morning and most of my lucids are around 6am.
