1. A method for processing at least one of reference glucose data or sensor glucose data, the method comprising:

  • receiving sensor data from a continuous glucose sensor, during a time period of continuous glucose sensing of a host, the sensor data comprising one or more sensor data points;

    receiving reference data from a reference glucose monitor, during the time period of continuous glucose sensing of the host, the reference data comprising one or more reference data points;

    forming, using a processor module, a matched data pair by matching at least one sensor data point to at least one substantially time corresponding reference data point;

    determining, during the time period of continuous glucose sensing of the host, using the processor module, a zone out of a plurality of predetermined zones into which the matched data pair falls based on a deviation of the sensor data and the reference data of the matched data pair and a user'"'"'s blood glucose concentration value as indicated by at least one of the reference data and the sensor data, wherein the plurality of zones comprises at least one zone of a first type and at least one zone of a second type; and

    processing, using the processor module, at least one of the one or more sensor data points and the one or more reference data points responsive to the type of zone in which the matched data pair is determined to fall.
