➠ Active insulin only reduces the correction portion of the estimate, not the food portion.
➠ For a current BG that is above the high target, if the active insulin is more than the correction
estimate, the correction portion of the estimate is changed to zero (0).
➠ For a current BG that is below the low target, if the active insulin is more than the correction
estimate, the active insulin is not considered.
