The present invention provides a method for supporting data driving a software process. The method comprises collecting data that describes a smoker’s cigarette consumption, using said data to generate a reduced smoking regimen, and implementing said reduced smoking regimen. These computationally less expensive functions are then combined, such as in a weighted andor offset mean, summation or difference to approximate the computationally expensive exponential function. The first and second light guide cables have distal ends positioned through the housing and are optically aligned but separated by a gap. The nutrition balance is for monitoring health and diet.
