1. A method of using a continuous glucose monitor and a glucose sensor that is in signal communication with the continuous glucose monitor through sensor electronics, the method comprising:
calibrating the continuous glucose monitor according to a self-calibration mode in which the calibrating is based on a priori calibration data;
determining a usage type of the continuous glucose monitor based at least in part on detection of a device coupled to the continuous glucose monitor or user input, the usage type comprising a therapeutic mode or an adjunctive mode;
receiving or determining usability data indicative of a usability of a glucose concentration measured by the glucose sensor;
comparing the received or determined usability data to one or more transition criteria to determine that the received or determined usability data has met or will meet the one or more transition criteria, wherein the one or more transition criteria are weighted based on the usage type of the continuous glucose monitor, wherein the one or more transition criteria are weighted for safety in the therapeutic mode and are weighted for convenience in the adjunctive mode;
responsive to the determining that the usability data has met or will meet the one or more transition criteria, causing a transition from the self-calibration mode in which the calibrating is based on the a priori calibration data to a user-dependent calibration mode which uses a calibration value from an external blood glucose meter, wherein the self-calibration mode does not use the calibration value from the external blood glucose meter; and
calibrating the continuous glucose monitor according to the user-dependent calibration mode, using the calibration value from the external blood glucose meter.
