1. A method for calibration of a continuous glucose sensor, the method comprising:

  • receiving, using electronic circuitry, sensor data from a continuous analyte sensor, the sensor data comprising one or more sensor data points;

    receiving and processing, using the electronic circuitry, calibration information to generate a calibration function;

    evaluating, using the electronic circuitry, a predictive accuracy of the calibration information to determine a predictive accuracy metric;

    calibrating, using the electronic circuitry, sensor data using the calibration function;

    comparing, using the electronic circuitry, the predictive accuracy metric to one or more thresholds; and

    processing, using the electronic circuitry, the calibrated sensor data to generate output, wherein the processing is performed differently depending upon the comparison of the predictive accuracy metric to the one or more thresholds, wherein the processing comprises controlling insulin delivery and/or insulin therapy instructions differently based on the comparison of the predictive accuracy metric to the one or more thresholds.
