1. A method, comprising:
- retrieving a current sensor sensitivity associated with an analyte sensor;
determining, using one or more processors, a difference between the current sensor sensitivity and a prior stored sensor sensitivity is not within a predetermined range;
determining, using the one or more processors, a new sensor sensitivity when the difference between the current sensor sensitivity and the prior stored sensor sensitivity is not within the predetermined range;
determining, using the one or more processors, if a difference between the new sensor sensitivity and one of the current sensor sensitivity or the prior stored sensor sensitivity is within the predetermined range; and
determining, using the one or more processors, a composite sensitivity based on the new sensor sensitivity and the one of the current sensor sensitivity or the prior stored sensor sensitivity when it is determined that the difference between the new sensor sensitivity and the one of the current sensor sensitivity or the prior stored sensor sensitivity is within the predetermined range.

8. An apparatus, comprising:
-
a data storage unit; and a processing unit operatively coupled to the data storage unit, and configured to, prior to calibrating an in vivo analyte sensor, retrieve a current sensor sensitivity associated with the analyte sensor, determine a difference between the current sensor sensitivity and a prior stored sensor sensitivity is not within a predetermined range, determine a new sensor sensitivity when the difference between the current sensor sensitivity and the prior stored sensor sensitivity is not within the predetermined range, determine if a difference between the new sensor sensitivity and one of the current sensor sensitivity or the prior stored sensor sensitivity is within the predetermined range, and determine a composite sensitivity based on the new sensor sensitivity and the one of the current sensor sensitivity or the prior stored sensor sensitivity when it is determined that the difference between the new sensor sensitivity and the one of the current sensor sensitivity or the prior stored sensor sensitivity is within the predetermined range. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15)
