What I did on the charts is this: I read off the Lilley-supplied charts serum insulin levels for H and R as functions of time. Across these I drew a baseline. After subtracting the baseline, I integrated under the curve to calculate a total Units-time value. The integral is simple the sum of each time-step mulitiplied by the average insulin level over that time step. When summed over the total time, this becomes essentially a measure of the total injected into the subjects. From this I calculated an unused insulin percentage by dividing the sum over all the time steps up to some particular time and dividing by the total summation. This is a % remaining to enter the bloodstream, i.e., the % unused. This same approach was used for both the H and R charts. Again let me apologize for this. I would have liked the presentation of this data to have been simpler and clearer so that I only needed one message to present it. I guess that is the liability of doing my emails after a full day of real work.
