T1 - ( T2 - T1 ) x 1.618 = 31871 ==> 2.618 x T1 - 1.618 x T2 = 31817
T2 - ( T2 - 32450 ) x 0.5 = T1 = 0.5 x T2 + 16225
==> -0.618 x T2 + (0.5 x T2 + 16225 ) x 1.618 = 31871 => 0.191 x T2 = 5618.95 Wrong!
==>Correct=> 2.618 x 16225 - 0.309 x T2 = 31871 ==> T2 = 34324 !!
==> T2 = 29418.6 ? T1 = 30934 ? ---> 實際應該 T2 = 34324,T1 = 33387
