The hbA1c does not really give an average. the function is non-linear 
and is weighted toward the higher values. Glucose molecules get stuck 
the the red blood cells and don't easily become unstuck. the result 
being that the average from a bg of 150 and 50 won't produce the same 
results with real glucose because the result will come out higher 
than a simple math average would predict.
