Basal Rate Differentiation

I was just wanting to see other peoples different basal rates. Since I have started coming out of my honeymoon period, the differences of basal rates are becoming more profound. Overnight I've had to increase to .7 units per hour. Initially I just kept the rates the same, but I noticed a low every single day around 2. I never got the spike I anticipated after my lunch at 11:15, so I assumed the basal rate was needed to be decreased before lunch. Changed basal rate at 8:00 am-5 pm, decreasing it by about .1 unit per hour, per week. Once I got to .4 units per hour, decided it to go ahead and do a basal test to check the afternoon. Skipped lunch, at 11:00am I was at 135, 12:00pm 133, 2pm 122, 3 pm, 125, 4pm 110. I will check in another hour to see, but this seems to be pretty good. I don't want to micromanage this thing, but I also want to be good at it to. So as it stands, I'm at .7 units all day except between 8:00am and 5:00pm which I am at .4. Seems like a big difference, and there's no "gradual" change, not sure if there's supposed to be. Anyone with a bigger difference than that? Is it worth picking a few hours and gradually stepping down from .7 units to .4 units in the morning and then back up to .7 in the afternoon?

12AM=.3U/hr; 3AM=.45U/hr; 7AM=.25U/hr; 4PM=.35U/hr, so not a lot of variability but it certainly makes a difference. I have an exercise pattern which is approximately 50% basal. Depending on the exercise, I normally run that basal from 1-2 hours before, and turn it off as soon as I finish exercising. And if I am eating anything with much fat, I will run a temporary basal (usually 150%) for about 2 hours, depending on how my blood sugar levels have been running that day.

I would not make any changes without first consulting your doctor, especially if you are just coming out of your honeymoon. I found that to be a very tricky time, when it almost seemed as if there might be some reserve of endogenous insulin which every once in a while kicked in and caused me to have some otherwise unexplained lows.
