1. An analyte monitoring system, the system comprising:

  • an analyte sensor;

    a processor module coupled to the sensor and configured to determine the concentration of an analyte based on a signal generated by the analyte sensor; and

    a user interface to provide analyte information to a user;

    wherein the processor module is configured to dynamically and intelligently match sensor data from the analyte sensor with reference data from a reference analyte monitor based on an evaluation of information associated with a time lag of the sensor data relative to the reference data during calibration of the analyte sensor, andwherein the processor module is configured to dynamically and intelligently match by estimating a time-correspondence between the sensor data and the reference data based on the information associated with the time lag.
