1. A system, comprising:
an transcutaneous glucose sensor having a proximal portion configured to remain above a skin surface of a user and a distal portion positionable beneath a skin surface of a user in a subcutaneous space, wherein the transcutaneous glucose sensor is configured to generate signals at a working electrode over a sensor session having a length of at least five days including a first day, a second day, a third day, a fourth day, and a final day, the generated signals associated with an in vivo glucose concentration; and
a sensor control unit comprising at least one contact in electrical communication with the proximal portion of the sensor, the sensor control unit configured to receive the generated signals and convert the generated signals to glucose concentration data using calibration data, the sensor control unit further comprising a transmitter configured to communicate the glucose concentration data to a receiver unit;
wherein the glucose concentration data has:
a first accuracy corresponding to the first day of the sensor session,
a second accuracy corresponding to the second day of the sensor session, and
a third accuracy corresponding to the fourth day of the sensor session;
wherein the second accuracy is higher than the first accuracy, the third accuracy is higher than the second accuracy.
