The max score is 160 and 19 (the max scaled score per sub test) is not a factor of 160. Therefore there has to be more to it than just summing the scaled sub test scores. I believe that the scored is derived by weighting the subtests by their perceived correlation with 'g' or general intelligence but I do not know the specifics.
