1. An insulin delivery system comprising:

  • a pump that is controllable to adjust insulin delivery relative to a baseline delivery rate;

    a sensor for measuring glucose levels of the patient;

    a controller coupled to the pump and sensor and configured to calculate insulin delivery based upon an autonomous modulation algorithm utilizing measured signals from the pump and sensor and configured to perform sequential averaging of insulin deliveries made by the system and a scheduled basal rate over a period of time; and

    a visualization and analysis tool engageable with the controller, the tool enabling the detection and display of at least one activity event in which the controller compares a scheduled insulin delivery to actual delivery of insulin by the system and determines the presence of the at least one activity event based on periodic sample averaging of both the scheduled and delivered insulin and wherein the at least one activity event is based on a ratio of a system-delivered insulin amount to the corresponding scheduled amount being less than or greater than a therapeutically relevant ratio.
