"Pumping Insulin" is an amazingly good book on insulin pumps. It contains clear instructions on how to adjust basal, bolus, and correction rates as insulin needs change. These tables are particularly valuable for parents of Type 1 diabetics going through puberty.
When my daughter got out of her honeymoon period, her A1C scores went from 6.6 to 8.7. "Pumping Insulin" gave me the information and tools I needed to bring her A1C back down to 7.4 in 3 months, despite further growth spurts.
One chapter has estimates relating total insulin requirements to approximate settings for Basal, Bolus, and Corrections -- while intended for "starting settings", this information works well for re-adjusting your pump's settings when everything is really off. The Basal rate checks are clearly described and tell you exactly how to adjust your pump settings. One chapter has suggestions on the lines of "if you are seeing this, try that".
