There's no reason to assume the peaks occured at the same time, hence
you cannot sum them and expect the total to be at 43.61


range1:   1,2,3,4,5,6,7      max==7
range2:   7,6,5,4,3,2,1      max==7
----------------------- sum
          8,8,8,8,8,8,8      max==8


max(range1)+max(range2) == 14 != 8
