[IP] Variable basals / ratios

It's trickier than that. Your body shifts gears in the morning when 
you feed it.  Try an experiment where you eat a high carbo breakfast.
and then again with low carbo and profile your bg's against expected 
bg rise for the bolus. i.e. don't use a standard breakfast, use 2! 
that are very different.  You should see a bias that will show that 
your body's insulin requirements have a hump that is really 
independent of the food eaten.
Given that everything else is stable, good nights sleep, standard 
wake time, nothing funny the nite before, etc..  The breakfast bolus 
can be broken  down into two components.

One that is relatively constant and another, with a STANDARD ratio 
that is directly related to the carbo intake.  I have successfully 
isolated and measured this for Lily. She knows that if she gets up 
after a certain time of day (about 7:30 or 8:00) and then eats, she 
is guaranteed to need an extra 2.0 units of insulin no matter how 
little or much she eats. If she gets up at 6:30, it is not needed. 
Simply a difference in metabolic response to the amount of rest an 
'getting the engine going'. If she doesn't eat, you don't see the bg 
rise. Curious eh?

This baffled me for quite a while until I decide to profile her with 
standard (repeatable) meals. Like the same bowl of cereal for a few 
days then something else like toast and eggs with a very different 
carbo load.

Try fiddling with the graphic basal rate model on the web site, you 
may be able to reduce the # basals without side effects.
