The exemplary embodiments may provide a correction factor (CF) for a user that is dynamically adjustable based on current glucose level. In some exemplary embodiments, the CF of the user is adjusted based on the current glucose level of the user.

This adjustment may cause the control system to increase the amount of insulin delivered to the user as the glucose level of the user exceeds the threshold. Similarly, the CF of the user may be adjusted based on the current target glucose level of the user or based on a combination of the current glucose level of the user and the current target glucose level of the user.
