I really want to urge you to follow the dosing protocol You do NOT slide your dose based on pre-shot numbers. I suspect you are going to see really wonky numbers by changing Martha's dose or skipping shots every other cycle. It would be better to lower the overall dose so you are comfortable shooting the same amount of insulin twice a day. Consistency is very important in order to maximize the effectiveness of Lantus.
It's also important to get a spot check during the PM cycle. With such a lovely AMPS, you have no way of knowing how low Martha's numbers went last night.
