For future reference...
I will feed LC first if numbers are above 50.
If numbers are in the 40s, I feed either LC or MC. This depends on where in the cycle the drop is an how much momentum is behind it.
If numbers are under 40, I feed HC.
That said, a lot depends on how carb sensitive Jake is.
When you get numbers below 40, you may want to test every 15 min. to make sure the numbers are responding to the food. We refer to this as lather, rinse, repeat. Once you get 2 consecutive tests where numbers are stabilizing (i.e., a surf in the 60+ range) or rising, test every 30 min. Once you get 2 consecutive tests with stable numbers, you can get a test in an hour. The reason for the frequent tests is that as the HC food wears off, numbers may bobble around.
