Claim 9:
10. A continuous glucose monitoring (CGM) device comprising:
a sensor configured to produce glucose signals from interstitial fluid;
a processor; and
a memory coupled to the processor,
wherein the memory includes a gain function stored therein, the gain function based on a plurality of sensor progression parameters of the glucose signals, each sensor progression parameter based on a point-of-interest glucose signal and a glucose signal measured prior to the point-of-interest glucose signal,
wherein the gain function employs at least one gain function ratio,
wherein the at least one gain function ratio is a first ratio to a second ratio,
wherein the first ratio is a ratio of a presently-measured glucose signal from the CGM device to a first previously-measured glucose signal from the CGM device,
wherein the second ratio is a ratio of the presently-measured glucose signal from the CGM device to a second previously-measured glucose signal from the CGM device,

wherein the memory includes computer program code stored therein that, when executed by the processor, causes the CGM device to:
measure and store a plurality of glucose signals using the sensor and the memory;
for the presently-measured glucose signal, compute the plurality of sensor progression parameters based on the presently-measured glucose signal and a plurality of previously-measured glucose signals stored in the memory;
employ the plurality of sensor progression parameters and the stored gain function to compute a compensated glucose value; and
communicate the compensated glucose value to a user of the CGM device.
