1. A method for generating analyte measurements of a host, the method comprising:

  • generating sensor data during a first time period using an analyte sensor coupled to a sensor electronics unit, wherein the sensor electronics unit is adhered to a body of a host;

    receiving, using a receiver in wireless communication with the sensor electronics unit, a reference analyte value generated by a reference analyte monitor;

    responsive to receiving the reference analyte value, determining a first estimated analyte concentration value to display using an immediate calibration algorithm that includes matching the reference analyte value to a sensor data point closest with respect to time, wherein the first estimated analyte concentration value is associated with the analyte concentration of the host at a point in time;

    determining a second estimated analyte concentration value to display using the reference analyte value and the sensor data for the first time period in a standard calibration algorithm that is different from the immediate calibration algorithm, wherein the standard calibration algorithm includes re-matching the reference analyte value to an optimal sensor data point or points, and wherein the second estimated analyte concentration value is associated with the analyte concentration of the host at the same point in time as the first estimated analyte concentration value; and

    displaying, on a display of the receiver, a numerical analyte value selected from the first estimated analyte value and the second estimated analyte value, wherein the first estimated analyte concentration value is selected as the displayed numerical value until the second estimated analyte concentration is available, and subsequently selecting the second estimated analyte concentration value to be the displayed numerical value.
