Systems, devices, and methods with duration-based adjustment of sensor data

A method of algorithmically processing glucose sensor data, comprising:

• collecting data indicative of environmental exposure of a glucose sensor during a duration of time before use of the sensor control device by the user, wherein the glucose sensor is configured to detect glucose levels in a bodily fluid of a user such that a first portion of the glucose sensor is configured to reside above a skin surface of the user and a second portion of the glucose sensor is configured to reside below the skin surface and in contact with the bodily fluid of the user;
• retrieving the data indicative of environmental exposure of the glucose sensor during the duration of time before use of the sensor control device by the user;
• determining a wear duration of the glucose sensor, wherein the wear duration corresponds to a duration of time after use of the sensor control device by the user;
• collecting, from the glucose sensor, sensor data including data indicative of a glucose level in the bodily fluid while the glucose sensor is in a position with the first portion of the glucose sensor above the skin surface of the user and the second portion of the glucose sensor below the skin surface and in contact with the bodily fluid of the user, the glucose sensor having been placed in the position with an insertion device, wherein the glucose sensor was electrically and communicatively coupled with processing circuitry of the sensor control device prior to placement of the glucose sensor in the position;
• algorithmically adjusting a calibration parameter of the glucose sensor with:
• a first function including a first adjustment parameter and a value representative of the wear duration, and one or more additional functions including a second adjustment parameter and a value representative of the environmental exposure of the glucose sensor during the duration of time before use of the sensor control device by the user;
• algorithmically processing the sensor data using the adjusted calibration parameter and to determine the glucose level in the bodily fluid;
• and
• transmitting the determined glucose level to a reader device communicatively coupled with the sensor control device and configured to display the determined glucose level.
