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, and predicting an analyte concentration value;

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

    responsive to receiving the reference analyte concentration value, determining a first estimated analyte concentration value to display using a first algorithm, wherein determining the first estimated analyte concentration value to display includes using the reference analyte concentration value in a first algorithm, the first algorithm including comparing the predicted analyte concentration value to the reference analyte concentration value;

    determining a second estimated analyte concentration value to display using the reference analyte concentration value and the sensor data for the first time period in a second algorithm that is different from the first algorithm, the second algorithm comprising a conversion function, wherein the conversion function is based on a matching of the reference analyte concentration value to sensor data; and

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

    using the first estimated analyte concentration value, the second estimated analyte concentration value, the predicted analyte concentration value, the reference analyte value, a rate of change of analyte concentration value, or a directional trend of analyte concentration value, to control an insulin pump to control an amount of insulin given to a diabetic user to evade a hyper- or hypoglycemic condition.
