1. An ambulatory insulin pump system, comprising:

  • a pump configured to deliver insulin to a user;

    a user interface including a display;

    a memory; and

    a controller in electrical communication with the pump, the memory and the user interface, the controller configured to determine an effective correction factor for the user by conducting a correction factor test, the correction factor test comprising;

    receiving sampled glucose level data of the user obtained during a specified time duration;

    causing the pump to deliver an initial insulin correction bolus to the user during the specified time duration;

    determining from the sampled glucose level data a decrease in the glucose level of the user during the specified time duration;

    calculating an effective correction factor for the user based on the decrease in the glucose level and an amount of the initial insulin correction bolus; and

    saving the effective correction factor in memory.
