1. A method comprising:
receiving sensor data conveyed by an analyte sensor comprising an analyte indicator;
using the sensor data to calculate one or more analyte levels;
receiving one or more reference analyte level measurements;
using the sensor data, the one or more calculated analyte levels, and/or the one or more reference analyte level measurements to calculate a degradation rate of the analyte indicator of the analyte sensor; and
setting a dynamic calibration frequency based on the calculated degradation rate, wherein setting the dynamic calibration frequency based on the calculated degradation rate comprises:
determining whether the calculated degradation rate is below a first degradation rate threshold; and
setting the dynamic calibration frequency based on whether the calculated degradation rate is determined to be below the first degradation rate threshold.
