1. A method for improving accuracy of a continuous glucose sensor (CGS), comprising:

  • calibrating the CGS at a first time;

    dynamically monitoring a CGS value and a rate of CGS change over time;

    determining, at a second time, whether a first condition is met, wherein the first condition is met if an absolute value of the rate of CGS change at the second time is less than a first predetermined value, and wherein the absolute value of the rate of CGS change is an absolute value of a first order time derivative of the CGS value;

    in response to the first condition not being met, maintaining the calibration of the CGS at the first time;

    in response to the first condition being met, determining whether a second condition is met;

    in response to a determination that the first condition and the second condition are met, calibrating the CGS at the second time.
