1. A method, comprising:
- determining periodically at a first medication delivery rate adjustment frequency whether to adjust a medication delivery rate;
monitoring a closed loop control operation including an analyte level associated with signal levels received from an analyte sensor at a predetermined frequency;
determining a variation in the monitored analyte level;
modifying the first medication delivery rate adjustment frequency to a second medication delivery rate adjustment frequency based on the determined variation in the monitored analyte level; and
determining periodically at the second medication delivery rate adjustment frequency whether to adjust the medication delivery rate;
wherein the modification to the first medication delivery rate adjustment frequency is performed dynamically based in part on the determined variation in the monitored analyte level.

13. A device, comprising:
-
one or more processors; and a memory operatively coupled to the one or more processors, the memory for storing instructions which, when executed by the one or more processors, causes the one or more processors to determine periodically at a first medication delivery rate adjustment frequency whether to adjust a medication delivery rate, monitor a closed loop control operation including an analyte level associated with signal levels received from an analyte sensor at a predetermined frequency, determine a variation in the monitored analyte level, modify the first medication delivery rate adjustment frequency to a second medication delivery rate adjustment frequency based on the determined variation in the monitored analyte level, and determine periodically at the second medication delivery rate adjustment frequency whether to adjust the medication delivery rate, wherein the memory for storing instructions which, when executed by the one or more processors, causes the one or more processors to dynamically perform the modification to the first medication delivery rate adjustment frequency based in part on the determined variation in the monitored analyte level. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28)
