The importance of monitoring
Evidence shows that the HbA1c achieved is dependant on the number of HbA1c daily Blood Glucose (BG) tests you make
Correlation Between HbA1c and Frequency of Blood Glucose Self-monitoring Under Insulin Pump Treatment
Results of a questionnaire* on diabetics with an insulin pump treatment in Germany in 1998/1999. 2481 data sets (Diabetes duration: 20 ± 11 years; Treatment with an insulin pump: 3 ± 5 years; Frequency of daily blood glucose self-monitoring: 5.4 ± 1.8; HbA1c: 6.9 ± 1.1 %)

To make pump therapy safe and effective you need to do 4 - 6 BG tests a day.
