1. A computer implemented method for execution using one or more processors, the method comprising:

  • receiving analyte data obtained from an analyte sensor in fluid contact with interstitial fluid under a skin layer;

    determining an analyte level in the interstitial fluid based at least in part on a nominal sensitivity associated with the analyte sensor and the received analyte data;

    determining a lag time constant associated with the determined analyte level of a user;

    performing lag correction of the determined analyte level based at least in part on the determined lag time constant;

    updating a rate of change of the analyte level;

    determining that the received analyte data has reached a predetermined count; and

    modifying the lag corrected analyte level based on the updated rate of change of the analyte level and the determination that the received analyte data has reached the predetermined count.
