Not quite sure which aspect of the basal profile the notion of working with or setting the actual profile in the pump part?
But this is my profile settings for part of my day,
Home 5am 0.3 6am 0.4 7am 0.5 8am 0.6 9am 0.6 10am 0.6
Work 1 5am 0.3 6am 0.2 7am 0.2 8am 0.2 9am 0.1 10am 0.1
Work 2 5am 0.3 6am 0.3 7am 0.3 8am 0.3 9am 0.3 10 am 0.3
Using these keeps my levels steady, I can flick from one profile to another miminising the adjustments/corrections at any one time...
So in your case you would create one profile to use on your day off that gives best control, then work out what your basal is up to when on an early shift to create your second, and then your late shift, then all you need to do is flick to what ever profile suits what you'll up too..
Can you see from looking at what I've done, how confusing and poor the out-come would be if I tried to cover all by using one profile... Because the adjustment or data I collected for being up home, would cause an hypo but if I used the data from a work day, I be high as a kite on a day off..
The easist way of achieving some clarity, get the basal setting for you day off sorted, by using only information collected/tested on that day.. if you have a hypo or high in work don't use this to make any adjustments to you basal.. (that will come later) then when you settled on your day off (you will have to ignore the frustrations work control might give you)
Then you tackle the most problematic shift first, you load all you settings from you home profile (main) into profile no 2, on your pump..
Now look at your past BG readings, from just before you go to work any in work, and try to see either a pattern or danger points of high or hypo's... This will give you some idea at what points you may need to make adjustments to the basal on this profile...
When doing this, I don't make any changes to start with, but use the TBR to see what sort of adjustment to make then review my data to see if it worked, then make the changes to the acutal no 2, profile...
To help keep it all as clear as possible when sorting it all out I keep all the data in separate record books, other wise one day tends to merge into another, and it isn't easy to see if the 22nd was a day off or the 23rd was either early or late shift....
If you still confused, let me know exactly which bit you are finding confusing..
